Metric vs. other measurement systems - chart

[jdurand]

To whom do you refer? I'm in Australia and I assure you that weight here is measured in Kg's

To pick nits, kg is mass, NOT weight. Pounds is force that's taken to be mass in the west.

ie: 1 kg of water is still 1kg in space or on the moon, but 1 pound of water changes even by your location on Earth.
