ABOUT LENGTH UNITS

Length is measured against the metre, the SI base unit, defined by the speed of light. Every unit here is stored as its exact number of metres, so a conversion is simply the input turned into metres and then into the target unit. The metric prefixes run the full modern range — from the quectometre (10⁻³⁰ m) to the quettametre (10³⁰ m), including the ronna and quetta prefixes added in 2022. The imperial and US units use their exact international definitions (an inch is exactly 2.54 cm), while astronomical units such as the light-year, astronomical unit and parsec, and sub-atomic scales like the ångström, Bohr radius and Planck length, extend the range in both directions. Historical and regional units — cubits, ells, versts, the Scandinavian mile — and playful ones like the smoot use common modern equivalents and can vary by source.
