Inch / Meter 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.
Meter
The meter is the unit of measurement par excellence since the origin of this unit comes from the Latin "metrum" and the Greek "metron" which mean measure. It is also this unit which gives its name to the diplomatic treaty which formalizes the decimal metric system: the convention of the meter, signed on May 20, 1875 by 17 nations, which today provides its basis for the International System of Units (SI).
