I'll say no more on that because I promised not to get political on this site.

How is this still a political issue? Does anybody seriously advocate abandoning SI units in science and engineering? Even UKIP aren't that daft!

Under British law it is ILLEGAL to use other than Imperial measures. The law dates from the 11th century and has never been repealed, therefore any NON IMPERIAL units of weight or measure used in the UK are illegal.
That's what makes it a political issue.

Not a lawyer, but pretty sure an existing law does not have to be explicitly "repealed", and newer legislation covering the same area will supercede it by default. Just saying, like...

This is the 21st Century, so leave the quill and the chains and furlongs where they belong in history, imperial and metric measurements have and I guess will be used side by side for years to come, in my entire working life spanning 45 years plus sheet materials have been sold in mm, timber also but still people refer to 8x4 sheets and 2x1 framing ??? Imperial will last for as long as individuals remember and use them I reckon, Law or no Law, Repeal or otherwise.

My query isn't about the law. But about real, practical applications of the SI system*. Within science and engineering SI is now ubiquitous, and anyone under the age of 50 will have been taught essentially nothing but the SI system in maths and science lessons. The benefits of using the same SI measurements are vast, not least of all because the Base 10 system works nicely with mathematical applications on computers such as spreadsheets and calculators.

Other than making people over the age of 50 feel happier, I can't think of any single practical reason why switching back to Imperial measurements makes sense.

In fact maintaining some older units, like calories and miles/hour, cause problems for science teachers. Joules are what's taught in school for the unit of energy, they're what's used in modern physics, and they fit nicely with other standard units like Newtons, kilograms and metres (i.e., one joule is the energy used exerting one Newton across one metre). But calories... for a start there's two of them, a physics one based on doing work and a nutritional one, the latter being a thousand of the "small" calories. So right there you have the confusion between a calorie you'd use doing an experiment and the calorie you see on a food packet. This confusion carries on with miles (nautical versus statute), gallons (including UK and US gallons), tons (again, US versus UK varieties) and so on.

Everyone on the planet agrees on what joules, metres, etc. should be (putting aside discussions on the best way to define them, which have varied as technology has improved).

Of course I don't have a problem with buying beer in pints or road signs with miles on them. Customary units in situations where precision isn't important is fine. But expecting schools to teach two sets of measurements is not realistic**, especially when one of them isn't compatible with decimals so can't be processed with a calculator or spreadsheet.

Over to you, D1042... why should Britain go back to miles, feet, pounds and British thermal units? What practical advantages would there be?

Cheers, NeMo

*What the layperson often calls the "metric" system, though they're not the same thing
**It's hard enough teaching the average British teenager a single set of measurements.

I used to stick my head in the sand but after moving to Spain I had to start using metric and now find it really easy to use and visualize.  It is so much better than using something like 63/64ths etc.  Think the distances took longest to assimilate as a mile was a mile but now kms are just as easy.

If we went fully metric (which I would support) it would have huge cultural
implications, having to change such things as

500 miles by the Proclaimers
16 tons by Tennessee Ernie Ford
A thing called love by Johnny Cash
The Charge of the Light Brigade poem
Terror at 20,000 feet movie
The League of Gentlemen
The Merchant of Venice (Pound of flesh)
The names of The Yardbirds, Michael Foot, Miles Davis

That's enough silly changes (Ed)

I mainly use Imperial measures and have to use my inbuilt "ready reckoner" to convert most things in the Builders Merchants etc
Its not that I'm "metric illiterate" just that  I can instinctively visualise say a piece of 2x4 or an eight of an inch - though I must say millimetres are a bit handier than some of the more obscure fractinos of an inch :) Then again that is what he thou is for.

Use of Metric was legalised in this country in 1897 via the 1896 Weights & Measures Act.

Interestingly perhaps, WO Bentley used the metric system on his cars from day one ;)

I agree with most of what you say and I think metric has an advantage over imperial, predominantly because of the "divisible by ten" factor, which is far easier for people's brains to cope with.

That said, we are where we are because of history. In my industry (aviation) we predominantly use metric, although feet are used for altitude measurements (except for one or two countries in the world) and if we wanted to move away from nautical miles then we'd have to completely rethink how we measure the earth, since it's inexplicably linked to minutes of latitude.

I'm not saying metric isn't the way forward, but in certain applications we have imperial for a very good reason, normally to do with how a system was built, and changing that system just isn't practical.

Where it is practical, I imagine we'll continue to shift to metric, which is fine by me.

Mixed units are in common use in aviation worldwide - altitudes are in feet (except for Russia & China), long distances are in nautical miles, while short distances such as runway lengths are in either feet or meters depending on local rules.

The International Space Station uses imperial units throughout, though participating countries can use some very odd metric values for their parts.

Specialised fields have their own peculiar units, though these are often just multiples of metric units: Angstroms, Barns, SNUs, etc.  Digital electronics goes even further and warps the metric system so that kilo is defined as 1024 instead of 1000.

And we as modellers need to be fluent in both systems since old plans, maps and other documents can be in imperial, often including older units like chains for curve radii.  And don't forget our bastardised hybrids like 2mm to the foot.

The nice thing about standards is that there are so many to choose from!

Not any more. The kilobyte is a multiple of the unit byte for digital information. The International System of Units (SI) defines the prefix kilo as 1000 (103); therefore one kilobyte is 1000 bytes. The unit symbol for the kilobyte is kB.

Even the Russians now use feet above transition level (whereby altitude is referenced to a standard atmosphere of 1013 hectopascals).

But for my 3/6d :-
I had to start off with slugs and stones and hundredweights and etc and ,, was very happy when we were converted to cgs unit working - phys, chem and math started to make sense !
Then we were converted to SI, didnt see the need mostly  but it was easy, usually just a shift of the decimal and a change of name.
But then the thought police moved in and removed bits of one's anatomy if one didnt use meaningless units like "Hertz" instead of the self-contained "cycles per second" (that any child can understand), Newtons and Pascals instead of xxxx and yyyyy ( :) go on, quickly now, without thinking fill in xxx and yyyy lol )

Another effect of being as old as I am -
in the lab I am quite happy with 20deg C but not sure if it is warm/comfortable enough to go and sit outside in the garden and watch the birds until I am told it is above 75F !

Agreed, though arguably the Imperial system using Base-12 is actually better in this regard. Metres don't divide nicely into thirds, for example, but feet do. The "divisible by ten" is, I believe, actually more useful for computers. While I'm sure you could invent a computer that worked in fractions, the reality is that modern computers do floating point calculations presenting their results as decimals with some sort of significant digit approximation. I'm struggling to imagine an easier way to enter (most) numbers than as decimals. About the only exception that springs to mind would be something using Base-60 like degrees or time. But even then, I'd assume the computer then turns your 27 degrees 57 minutes and 12 seconds into some sort of decimal before it does the calculation required.

Totally agree. I've got a computerised telescope that's set up to use the equatorial coordinate system, which uses a bizarre mix of coordinates, right ascension (hours, minutes and seconds) and declination (degrees, arc minutes and arc seconds). Makes total sense given the history of astronomy and how people used to locate objects and compensate for the Earth's rotation, and these coordinates are what you'll find in an astronomy book. But at the same time, the telescope itself isn't polar aligned but uses a simple horizontal (alt-azimuth) mount instead, so the computers turns the RA and Dec values into an entirely different set of movements presumably using decimalised altitude and azimuthal movements. Since computers can make very accurate calculations on the fly, the RA and Dec approach doesn't really serve any practical purpose, even though it remains the standard for human beings reading books or looking on maps.

Indeed. Fiddling with shapes and sizes that are solidly entrenched is only useful if there's a practical benefit. I honestly couldn't care what sizes are used for plumbing fittings, rifle ammunition or book publishing since those things only really matter to people working in those jobs/professions. It's the reactionary stand sometimes made, that "the metric system" is all about Europe telling British people what to do that gets me cross. It's not. British scientists and engineers compete very well on the world stage, and trying to turn the clock back by teaching British youngsters about feet and pounds instead of metres and kilos will only damage that success.

PS. I've been told the Australian broad gauge was implemented specifically to avoid what was, in the 1840s, the "English" standard gauge. Irish settlers in Sydney wanted nothing to do with England, so they deliberately plumped for the Irish gauge* of 5'3" (a nice round 1600 mm, as it happens). By the time the railway networks of Australia were starting to join up, the 1880s, the different gauges started to create real and expensive problems. There are still bits of the network that are broad gauge, but most was gradually converted to standard gauge.

*Ironically, the Irish gauge was enforced by an act of the British Parliament in 1846.

Ah, but the great benefit of Kelvin is you don't need to figure out where the degree symbol is on your keyboard... though oddly enough on a Mac it's option-K, presumably because K is for Kelvin, which is totally paradoxical for the precise reason you give above! It's easy to remember though, which is nice.

My O-level physics teacher was a chap called Mr Channing, and he used to tell us all sorts of stories that, in hindsight, might not have been 100% accurate. But one I always liked was how Fahrenheit determined his scale as 0 for when the Baltic froze over and 100 for the blood coming from a freshly killed pig.

I believe the later definitions are slightly different (freezing point of brine vs. human body temperature at 96) but Mr Channing's story has stuck with me for 30-odd years!

When the newest car came a couple of years ago the top of the steering wheel obscured the speedometer so I couldn't see any speeds in MPH between 40 and 100.

I could however see the KPH part of the dial so got used to, for example, 100 KPH being 62 MPH which in the UK is a little over the standard for most A roads.

Then recently the garage came to collect the car and the first thing the guy did was to operate a lever so he could move the steering wheel up or down to suit his driving position.

Having now learned that trick :-[ I'm now back to good old MPH.

All good points! Just picking up on why I think people hark back to the "old days" for imperial (and I'm generally not one of them, except for one or two measurements);

I feel people have an emotional attachment to all sorts of things, things which are familiar to them. This includes measurements, whether it be distances, weights, currencies and so on (ok, currencies are slightly different, in that there's the whole question of sovereignty behind it). The level of emotional attachment, I feel, depends upon how intimate you are with the measurement in question (e.g. plumber, carpenter, scientist will have different levels of attachment, and possibly different views).

Additionally, I think age comes into it. People who were brought up in one system don't like change. They identify with a certain system, it's part of culture and identity. That doesn't mean we shouldn't change to what makes sense, I'm just trying to shine some light on why there might be resistance from smne people, which I think is understandable.

I shall never ask for anything other than a pint of beer or milk. That's because I'm intimate with those measures for those goods. I'm quite happy driving in most countries with km/h or using 1000 fils instead of 100 pence.

Interesting what you say from the perspective of computing.

Yes, I  have to laugh at that car thingy which my rels and old mates seem to carry around with them. Hit it on my recent visits.

However, back on topic.... the global scientific community uses metric, and having being involved with physics education for most of me life, as far as I'm concerned, that is that. End of story.

I can assure everyone that it's easier working with kilograms, Newton metres, etc than things like Dynes, foot poundals.... what the heck were they?  :worried:

I still use either system --or even a mixture-- of both when measuring length  etc. I just use whichever is easier to give an accurate result.
For quick easy rough calculations I always think of
1 kilo or litre being near enough 2 pints
1 metre being approx. 3 feet or one yard
then if I need to go closer than that I do a proper conversion.
A  handy on line conversion link is

My ex was working in the Post Office at the time.  She used to come home close to tears over that period.  She had no problems with the change over personally, but dealing with scores of customers every day who did ('specially on pension day!) was just a mind blower.

When I am looking at it baseboard size and radiusses etceral I use imperial, but if the track does not quite meet up I swap to mm to see how far off it is !

My only beef with SCARM is that I have to use two fingers (CTRL and U) to effect the swap, keep meaning to ask Mixy if we could design in a single hot-key (or at least two that are close together ie. do it one-handed )

I shall never ask for anything other than a pint of beer or milk. That's because I'm intimate with those measures for those goods. I'm quite happy driving in most countries with km/h or using 1000 fils instead of 100 pence.

You'd be happy in Japan - overseas beer is often sold in pints, you just have to be careful to distinguish between the lily-livered US pint and the proper one.

Unfortunately for you however, milk comes in 500ml tetrapaks (and I have yet to see a larger size). I know a pint is 568ml because it was always printed on the milk bottles (do they have those, and milkmen, any more?).

The only imperial measurement I feel compelled to use is miles when in the UK, kilometres just don't seem right there.

To this day I fail to grasp the Avoirdupois system.

Yes, and yes ;)

Milkmen are a dying breed though because it's so much more expensive having milk delivered than buying from a supermarket. Glass bottles are still about in a few places but most milkmen deliver in poly-bottles now. Almost gone is the whirr of an electric float accompanied by the clanking of the bottles.

I don't remember it, but I admire it. It was a combination of a Base-12 system and a Base-20 system, i.e., 20 shillings of 12 pence each. So you end up with 240 pence to the pound.

Sounds terrible, but for a world doing mental arithmetic, it was brilliant. The factors of 240 are 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240. That means can share one pound neatly into 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120 or 240 parts!

You can't do that with decimal currency. 100 only has seven factors: 2, 4, 5, 10, 20, 25, 50, so only seven ways it can be shared equally.

Hi Keerout

That above incident was actually due to a fuel leak and the subsequent transfer of fuel. I'm not aware of measurements being related, but please share any further info. you have. You are indeed correct in that it made a landing on a military airfield in the Azores. That was Lajes.

Feel free to send me a private message if we're taking this too far off topic.

Not quite, the basic currency unit the pound stayed at the same value, the decimalisation
was just cutting the cake in a different way, whether it was 100, 200, or 240 pence to the pound.

You don't remember the subtle price increases and the 'rounding up' that happened? :confused2:
Title: Re: Imperial vs Metric
Post by: Agrippa on October 05, 2015, 12:01:10 PM
It happened during a period of rampant inflation, the rounding up would should
only have amounted to a few pence and prices would have gone up anyway.
Any subtle price increases were offset by scrapping a mediaeval system and
at the same time the guinea which a big con used by lawyers etc  was wiped out.
I was working in an accountants office at the time and decimalisation made
the work much easier despite the old fogeys moanin and groanin about the good
old days.

That's slightly different to devaluation. Partly caused by the problem of 2d = 1p but 5p = 12d. Rounding up also happened when the half penny was got rid of.

Let's face it, if you were selling stuff, would you round up or down? ::)

My dad told me about this, many, MANY times.

But the problem was that the background level of inflation during the 70s meant that prices went up quite frequently, so it's hard to say whether the overnight rise in prices was really traders ripping off customers on the one hand or the effect of inflation on the other.

The main thing about decimalisation, which by the way is nothing to do

years before it did. To people who weren't around at the time the £sd
