When converting metric to US length units most online converters would tell you that 180cm is 70.8661417 inches. This is pretty much useless, because most people in US would say 5'10"
After trying to find converter which would give you 5'10" I finally put together very simple one myself.
The simple form below convers between metric and US length units. Understands input like: 10m, 25cm, 30.6mm, 5ft, 30in, 5'10"
