1 mile = 1.61km [kilometres]
1 stone = 6.35kg [kilograms]
1 pound = 454g [grams]
1 ounce [oz] = 28.3g
39″ [inches] = 1 metre
1 yard = 36″
1 lb [pound] = .45kg
With regards weight, it is more common in the US to use pounds rather than stone.
In the UK more people are using kgs for weight than before.
