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.
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.
