About these units
Furlong (US Survey) (fur (US))
The US Survey Furlong is defined as 660 US Survey Feet (~201.168 meters), exactly 10 US survey chains. It was historically used in land measurement, agriculture, and railroads. Furlongs remain relevant for interpreting historical property layouts and land grants, particularly in rural and agricultural contexts. The unit's convenience derives from its direct relationship with the acre and chain, facilitating rapid calculation of large land areas. While the furlong is largely obsolete in modern measurement, it persists in legal and historical survey references, bridging imperial traditions and contemporary land-use documentation.
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.
