Metrication

Good old Lord Geoffrey Howe was on the TV this morning advocating that the UK should proceed further with metrication as he feels that we are stuck in the middle of two different systems at present, and out of sync with most of the rest of the world. For example we buy petrol in litres and measure consumption in miles per gallon, buy draught beer by the pint, but bottles by the litre, etc etc.

Thinking about it, if one takes this to its logical conclusion we should metricate all measurements for the benefit of Joe Public. In particular, we could benefit from a decimal form of time. So we would have 10 hours in a day, and 100 minutes in an hour. Thus one new minute would be the equivalent of 1.44 old minutes. With 100 new seconds to a new minute, one new second is very nearly the same as one old second. This would make it much easier for children to learn the time, to calculate differences in time, etc and significantly improve punctuality.

On a nautical theme, we should also metricate Latitude and Longitude. So instead of 360degs around the equator, each of 60 minutes etc, there will be 100 degrees, each of 100 minutes. So one new minute of longitude is 2.16 old minutes. Then decimal fractions of a minute would be simpler, and calculations of distance across the planet, would be very much of easier.

Of course, this would result in a complete redrawing of charts, but they all get updated over a period of time anyway, so not a big problem. Secondly, GPS systems would need to upgraded but this should be a simple software or firmware change.

Assuming everybody agrees, I will drop a note to Lord Howe to seek his support.

Sorry, but you've missed a trick. If you make the distance from equator to pole 100 degrees, each with 100 minutes, then the nautical mile becomes the kilometre. That's what the French scientists planned when they produced the original metric system.

There will be riots in the streets

Last time they changed the calendar there were riots as people believed the state had stolen part of their life.

I think to make this feasible we will have to be told by a celeb that this is ok, hopefully one under 20 years old. That would give it a stamp of approval.

Re: There will be riots in the streets

You're thinking of Posh and Becks arent you? They could give the case intellectual credibility /forums/images/icons/smile.gif

Except the French never related it directly to angles, as far as I'm aware. They took the distance from pole to equator to be 10,000,000 quoi ques and worked backwards from there to derive the Moulin-Rouge-sexy-leg metre. The Germans, on the other hand, divided a circle into 400 grads which is neither metric nor logical.

The metre is used in our OS mapping as the basis for grid co-ordinates and (despite the odds) has proved itself to be a useful unit for us seafarers also. How many of us still work in fathoms?

Each to his own, and you'll forgive me if I continue to calibrate my log in furlongs per fortnight.

I thought that the Metre was defined as the wavelength of white light?

<hr width=100% size=1>my opinion is complete rubbish, probably.

White light is a mixture of many wavelengths hence the cunning French could not be faulted on this.

One of the original definitions was based upon a wavelength of krypton 86 radiation.

This was later replaced by the definition of the length of the path travelled by light in vacuum during a time interval of 1/299 792 458 of a second - wavelength is irrelevant as all light travels at the same speed

Wonder how deep they had to dig to come up with this nonsense? I get the impression monsieur Le Metric was more interested in powers of 10 and would take the consequences later, n'est ce pas?

The Irish show all their signposts and distances in kilometres (apart from a few) but have all their speed limits in miles per hour. I think this is a rather refreshing idea...
Er, a bit like having your distances in miles but selling your petrol by the litre...
Oh bugger..

It's no longer in the hands of the french, but an international committee. The history of the definition is:

"The legal definition of the metre has changed throughout time, following evolutions of science and the constant improvement of measuring tools. The precision of the measurement was thus made more and more accurate, but the length of the metre never changed:
Aug. 1, 1793: 1st definition. 1/10 000 000 of the northern quadrant of the Paris meridian (5 132 430 toises of Paris, from the north pole to the equator).
Apr. 7, 1795: 1st legal definition. A second measure is made along the Dunkirk-Barcelona axis (5 130 740 toises of Paris). Jun. 9: Provisional metre bar constructed in brass by Lenoir.
Jun. 6,1799: Definitive prototype metre bars and kilograms constructed in platinum. Dec. 10: 2nd legal definition. 3 feet and 11.296 lines of the toise of Paris (shorter of 0.144 line than the 1795 measure, and without the "meridian" definition). Metric system compulsory by law in France.
1889 Paris General Conference: 3rd legal definition. Length between both axis of two lines on the International prototype metre bar, made of platinum-iridium (90% Pt, 10% Ir), cross section X, at a 0 °C temperature. French legal standard metre was copy nº8 of the International prototype.
Oct. 14, 1960: 4th legal definition. 1 650 763.73 wavelengths in vacuum of the orange-red light radiation of the krypton 86 atom (transition between levels 2p10 and 5d5, 100 times more accurate than the 1889 definition).
Oct. 20, 1983: 5th legal definition. Length traveled by light in vacuum during 1/299 792 458 of a second. "

Re: Brendan - n\'est ce pas!

Quite right. I've been puzzling over Paul Lomax's post in Website feedback forum, and can't make head nor tail of it. I thinki perhaps he's been tied up by burglars, and is trying to attract attention!!

a) That means the retirement age going to 100 (which the government will surely love)!

b) Regardless of how you measure speed, the Police will still do you!

Sometime in the dim distant past I was told the USA past a bill introducing metrication some were around 1876, but it still has to be implemented. In fact they still, or till recently, worked in fractions of inches on engineering drawings, so still have to introduce decimals yet.
Now what about this flat earth theory???????
