Inch / Centimeter Units Definition
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.
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.
