How the UK works (or doesn't)?
The metric conversion:
"Everything you buy is measured in metric, so sugar is marked as say 500g bag, or a beer bottle is 330ml, but they never bothered with the roads. So I drive a car that measures temperature in Celsius, speed in mph, fuel consumption in mpg, and I buy petrol by the litre.
Some things have stuck, too, like beer is still served in pints, height is mostly measured in feet, but while most people measure weight by stone and pounds some do in kg. "
I find this fascinating, and in the bright side, it has trained me to be naturally good at translating kgs. to pounds and kms. to miles and so on when I see the different measures all over the internet.
The one thing I still have to look up a google converter for is Celsius to Farenheit.
