History of Length Measurement
The Evolution of Measuring Length
From ancient methods to modern standards
- Ancient civilizations used body parts like hands and feet as units of measurement.
- The cubit, based on the length of the forearm, was used in many ancient cultures.
- The metric system was developed during the French Revolution for standardization.
- The International System of Units (SI) was established in 1960, with the meter as the base unit of length.
- Today, the meter is defined by the speed of light in a vacuum.
