>>4350272Measurements for length, distance, and elevation are much more uniform in metric tho, as are measurements for weight and displacement.
1 gallon US - 3.89L
2.2lbs - 1Kg
1 inch - 2.54cm (25.4mm)
39.37 inches - 1 meter (100cm)
1 mile (1700-ish yards) - 1600m
It's just a matter of preference for me, I tell people the distance of things in km a lot by accident sometimes.
