Length units are fundamental measurements used to quantify distance or dimension. Throughout history, different civilizations and cultures have developed various systems of measurement, which explains the diversity of units we use today.
The metric system, used by most countries worldwide, is based on the meter as its fundamental unit of length. Originally defined as one ten-millionth of the distance from the North Pole to the Equator, the meter is now precisely defined using the speed of light in vacuum.
The imperial system, still commonly used in the United States and a few other countries, uses units like inches, feet, yards, and miles. These units have historical origins, often based on human body parts or practical measurements from daily life.
