Foot / Centimeter Units Definition
Foot
The foot is a unit of length of approximately 30 centimeters, corresponding to the length of a human foot of approximately size 45.In Antiquity, the foot was regularly divided into sixteen fingers or four palms. The Roman foot was 29.64 cm.Since the Middle Ages, the foot was also divided by twelve, which gave the inch. The foot of the King of France was 32.48 cm (size 48¾) and the Anglo-Saxon foot is 30.48 cm.
Centimeter
The centimeter is in common popular use: it allows to represent in a simple way dimensions of human size (less than the meter).In the scientific field, we prefer the meter (base unit of the International System) or the millimeter (widely used in mechanics) to represent lengths of these orders of magnitude.
