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.

Arpent

An arpent is a traditional unit of length and area used primarily in French-speaking regions, especially in parts of Canada (like Quebec) and Louisiana in the United States. It originated in France and was commonly used in land measurement and agriculture.

  As a length, one arpent is approximately 192 feet (about 58.47 meters), though it varies regionally.

  As an area, an arpent is roughly equal to 0.84 acres or about 3,400 square meters.

  
  

The arpent was important for defining land parcels during French colonial times and is still referenced in legal land descriptions in some areas today.
