About length units

Length sits at the heart of every other measurement: speed, area, volume, even energy in some derivations. Most everyday work bounces between metric (mm/cm/m/km) and imperial (inch/foot/yard/mile), with the nautical mile reserved for marine and aviation contexts. The meter has been the SI base since 1799, redefined in 2019 in terms of the speed of light.
