About these units
Kilometers
A kilometer (km) is a unit of length in the International System of Units (SI), equal to 0.6214 miles. One kilometer is one thousand meters.
The prefix "kilo-" means one thousand. A kilometer is defined by 1000 times the distance light travels in 1/299,792,458 seconds. This definition may change, but a kilometer will always be one thousand meters.
Kilometers are used to measure distances on land in most countries. However, the United States and the United Kingdom still often use miles. The UK has adopted the metric system, but miles are still used on road signs.
Fermi
A fermi (fm) is a unit of length used primarily in nuclear and particle physics to measure extremely small distances. One fermi is equivalent to 1 × 10^(-15) meters or 0.001 femtometers.
The fermi is defined as one femtometer, making it a convenient unit for expressing the sizes of atomic nuclei and subatomic particles.
Fermis are used in fields such as nuclear physics and particle physics to describe the scale of atomic nuclei and the range of fundamental forces. The unit provides precision for measuring distances at the subatomic level and understanding nuclear and particle interactions.
