Foot

Historically, many cultures—Greek, Roman, English, Chinese, French—used variations of the “foot” based on body measurements, ranging roughly from 250 mm to 335 mm. In 1959, these disparate values were unified into the modern international foot of exactly 304.8 mm.

Feet remain standard in the U.S., Canada, and the U.K. for measuring height, room dimensions, field lengths, and aviation altitudes. In these regions you’ll hear travel distances, building plans, and personal heights expressed in feet and inches.
Meter
개요
A meter (symbol: m) is the SI base unit of length, defined as the distance light travels in 1/299 792 458 second. This constant-based definition replaced earlier Earth- and artifact-based standards, ensuring universal precision.
