Historical Context of Measurement Systems
The use of inches versus centimeters dates back centuries.
-
Inches: Originating from Anglo-Saxon measurements, an inch was initially based on the width of a human thumb. It was standardized during the reign of King Henry I of England, setting the inch at 3 barleycorns or approximately 2.54 cm.
-
Centimeters: The centimeter is part of the metric system, which was developed in France during the French Revolution, with the aim of creating a universally accepted measurement system. One centimeter was set as 1/100th of a meter, with the meter originally defined as one ten-millionth of the distance from the Equator to the North Pole along a meridian through Paris.
