Foot / Inch 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.
Inch
The inch (symbol: ″ (double prime) or po in French-speaking Canada) is a unit of length dating back to the Middle Ages.Its dimensional value has varied over time, across regions and across countries.Since 1959, following an English compromise, the English inch — also called the “international technical inch” — has been exactly 2.54 cm, or one twelfth of a foot or one thirty-sixth (1⁄36) of a yard. For historical reasons, other definitions of the inch are still in force in certain areas.
