... the USA should switch from inches, miles, gallons, Fahrenheit, etc to cm, km, litres, Celsius?

... the treffic in UK and Australia should be on the right side like in the rest of the world?

Jake
Yes I think that the USA should change its measurement ( inches, feet, lbs ....) into Cm, Gr, KG ..... because their measurement is messed up and mathematically incapable and unfit.

to have one foot, you need 12 inches, why 12 and not 100 or 10 to make it simple?

same thing with pound, to have one pound you need 12 Ounces (OZ) why is that??? I really don't like it, because it doesn't make it easy for people to measure including Americans themselves. Although they agree that the international measurement units are Kg, meter... they still didn't change it, the only good thing that was done lately, is to add the European measurements side by side with the american measurements, for example a gallon of milk has both measurements (Gallon/... Liter)

Also The UK should change their way of driving, it's causing them accidents and fatalities every year, just because they want to feel unique. sorry but that should be changed too.

In terms of population about one third of the world drives on the left. See here for full details: http://users.pandora.be/worldstandards/driving%20on%20the%20left.htm#leftdriving

Driving on either side of the road is equally dangerous. For any country to change with the amount of traffic there is today and the number of road signs to be moved would be prohibitively expensive, and probably actually cause accidents.

Hi Forbers,

If so, let me ask you, how come that just in UK on the streets by the crosswalk (zebra crossing) is written: "WATCH RIGHT"?

Yes, changing the traffic will be a problem. It is possible however, when my family and I went for a visit to England we thought driving on the left side was weird to the begining, however you get used to it pretty quickly.

The costs may be a problem but I think, it will have to be changed sometime.

Best wishes, Jake
So perhaps the rest of the world should change and join us on the left if the only point is to have unity between all countries?

Anyway, I think that as long as there aren't any land borders with countries driving on the 'other' side, (can you picure it? lol) it doesn't make any difference which side a country drives on.
1) Yes

2) No, I like to drive on the left here in Italy as well. [6] (kidding) Emotion: big smile

LOOK RIGHT is written on the road at pedestrian crossings on a one way or multi-laned street to warn of traffic coming from an unexpected direction. Believe it or not but just about the whole population that is allowed out on its own does know what side of the road cars drive on.

16 actually.

In the UK the metric and avoirdupois systems were used together for a time to let people get used to them.

The older systems arose from units that were of practical use. Thus a good bag of potatoes weighed a stone; a sack of wheat was a bushel and a sack of coal weighed a hundredweight.

The metric system is easier for children to learn, but suffers from the problem that 10 is only divisible by 2 and 5, whereas 12 is divisible by 2, 3, 4 and 6. A third of a foot is exactly 4 inches, whereas a third of a meter is 33.3333333333333333333333333333333333333333333 and so on centimetres
