For twenty years now I've been hearing how metric will be the way of the future, it doesn't seem to be happening
Actually it
has happened. No many country still use the imperial system in an official capacity and I suspect that 95% of all the elementary students across the world have been taught the metric system.
The US are sort of a metric anomaly.
For the metrically challenged, it's very simple; You just have to figure out what is 1 meter (a bit over 3 feet, a little more than a yard) and then everything falls into places.
The basic units are meter for lenght, liter for volume and gram for weight.
Common prefixes modify these units as follow:
Kilo means 1000
Hecta = 100
Deca = 10
Deci = 1/10
Centi = 1/100
Milli = 1/1000.
Therefore a kilogram is a 1000 gram and a centimeter is 1/100 meter.
A liter is one cubic decimeter, or a 1000 cubic centimeter (10 cm X10 cm X10 cm).
A liter of water weight 1 kilogram. A ton is a 1000 kilogram.
Oh, and celsius degree; Water freezes at 0 degree celsius and it boils at 100.
It's childishly easy to memorize.
