A Brief History of Length Measurement

Length measurement has evolved over thousands of years. Ancient Egyptians used body parts like the cubit (elbow to fingertip), while Romans standardised the foot. The metric system was introduced during the French Revolution to bring order and universality, defining the metre as one ten-millionth of the distance from the equator to the North Pole. Today, the metric system is the global standard in science, with the imperial system still commonly used in the U.S. and a few other countries.
