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.

Long Reed

The long reed is an old English unit of length used primarily in measuring land, especially in agriculture and surveying. It is traditionally equal to 16.5 feet or 5.03 meters.

The long reed was used alongside other units like the rod, pole, and perch, often interchangeably, to measure distances and plot boundaries.

Key points:

1 long reed = 16.5 feet ≈ 5.03 meters
Used historically in land measurement and agriculture
Equivalent or similar to the rod, pole, or perch
Important in English customary measurement systems

Though obsolete now, the long reed is part of the rich history of traditional English measurement units.
