About these units
Feet
A foot (symbol: ft) is a unit of length used in the United States, the United Kingdom, and Canada. One foot is equal to 0.3048 meters.
The foot originated from various units used in ancient civilizations. Its current definition is based on the international agreement of 1959, which standardized it to exactly 0.3048 meters.
Feet are commonly used to measure height, length, and short distances. Despite the global shift to the metric system, the foot remains in use in these countries.
Femtometers
A femtometer (fm) is a unit of length in the International System of Units (SI). One femtometer is equivalent to 0.000000000001 meters or 1 × 10^(-15) meters.
The femtometer is defined as one quadrillionth of a meter, making it a very small unit of measurement used for measuring atomic and subatomic distances.
Femtometers are commonly used in nuclear physics and particle physics to describe the sizes of atomic nuclei and the ranges of fundamental forces at the subatomic level.
