About these units
Furlong (fur)
A furlong, equal to 10 chains or 660 feet, originated as the distance a team of oxen could plow before needing rest. Its name derives from "furrow-long," indicating the length of a typical plowed furrow in medieval agriculture. This agricultural basis linked the furlong to the acre: a rectangle one furlong long and one chain wide equaled one acre in area. Today, the furlong is most notably used in horse racing, where race distances are often measured in furlongs rather than miles. This tradition reflects both the unit's historical importance and its suitability for describing moderate distances. While archaic in most contexts, the furlong remains a culturally iconic measure that connects modern sports to medieval agricultural practices.
Angstrom (Å)
The ångström, equal to 10⁻¹⁰ meters, is traditionally used to measure atomic scales, bond lengths, and wavelengths of electromagnetic radiation, particularly in the X-ray and ultraviolet regions. Although not an SI unit, the ångström persists because it aligns conveniently with many natural atomic dimensions — hydrogen's typical bond lengths, for example, are close to 1 Å. Scientists in crystallography, astronomy, materials science, and spectroscopy routinely use ångströms when describing the spacing between atoms in a crystal lattice or the wavelength of certain spectral lines. The convenience comes from avoiding unwieldy decimals: instead of writing 0.154 nm, one may write 1.54 Å. While modern research increasingly prefers SI nanometers or picometers, the ångström remains deeply embedded in scientific traditions and continues to serve as a practical shorthand for atomic-scale measurements.
