Hand
A hand is a unit of length equal to 4 inches.
History/Origin
The hand was originally the width of a man's hand, including the thumb. It was standardized to 4 inches for measuring the height of horses.
Current Use
The hand is still used today to measure the height of horses.
Planck Length
The Planck length is the smallest possible unit of length in the universe, approximately 1.6 x 10⁻³⁵ meters.
History/Origin
The Planck length is derived from fundamental physical constants and is named after the physicist Max Planck. It is a fundamental unit in the system of Planck units.
Current Use
The Planck length is a theoretical concept used in quantum gravity and cosmology to describe phenomena at the smallest scales of the universe.
