Question

why is foot not used as a standard unit of length​

Answer 1

Answer:

A pace or a footstep cannot be used as a standard unit of length because the length of footstep, forearm length and hand span of different person is different. ... So footsteps and other such measuring systems cannot be use as standard unit.

Answer 2

Answer:

Feet and inches are used as a way to measure length too, but it is only done so in america. this is known as the imperial system. The rest of the world uses the metric sytem(cm, m, km) as it is much more reliable and hence it is an SI unit of length measurement.
