Understanding the Basics of Measurement Systems
What Are Centimeters and Inches?
Centimeters (cm) and inches are units of length used in different measurement systems. The metric system, which includes centimeters, is widely adopted worldwide, especially in scientific, medical, and everyday contexts in most countries. Inches belong to the imperial system, predominantly used in the United States, Liberia, and Myanmar.
- Centimeter (cm): A metric unit of length, where 1 centimeter equals one-hundredth of a meter.
- Inch: An imperial unit of length, traditionally based on the width of a human thumb, with standardized definitions now in place.
Historical Background of Measurement Systems
The metric system emerged during the French Revolution in the late 18th century, designed to create a universal, decimal-based measurement system. The inch, on the other hand, has roots dating back to ancient times, with various definitions over centuries. The modern international inch is precisely defined as exactly 2.54 centimeters, a standard established in 1959.
