Engineering Unit Converter
Engineering unit conversion across eight dimensions — length, area, volume, mass, force, pressure/stress, moment and density — with one-click **metric ⇄ imperial** switching. Use it whenever a project mixes imperial practice (ft, in, lb, psi, kip) with SI drawings.

METHOD
Conversions use fixed defined factors: 1 in = 25.4 mm, 1 ft = 0.3048 m, 1 lb = 0.45359237 kg, 1 psi = 6.894757 kPa, 1 kip = 4.448222 kN.
- The factors are international definition values (1959 International Yard and Pound Agreement) and introduce no rounding error.
- Distinguish the mass unit lb (pound) from the force unit lbf, and the US ton (2000 lb) from the metric tonne (1000 kg).
