Femtometer

A femtometer (fm) is a unit of length in the metric system, equal to one-quadrillionth of a meter (1 fm = 10⁻¹⁵ meters). It is also known as a fermi, named after the physicist Enrico Fermi. Femtometers are used to measure extremely small distances at the subatomic level, such as the size of protons, neutrons, and atomic nuclei. For example, the radius of a proton is about 0.84 femtometers. This unit is commonly used in nuclear physics and particle physics, but it's far too small for everyday measurements.

Centimeter

A centimeter (cm) is a unit of length in the metric system. It is commonly used to measure small objects or short distances. One centimeter is equal to one-hundredth of a meter, meaning 100 centimeters make 1 meter. In everyday life, centimeters are used to measure height, the size of books, or dimensions of furniture. For example, a pencil might be about 15 cm long. The symbol for centimeter is "cm", and it is widely used around the world, especially in countries that follow the metric system. Rulers and measuring tapes often include centimeter markings to help with precise measurements. The centimeter is a practical and easy-to-use unit that helps in getting accurate sizes for various items.
