Force Unit Converter

  • SI unit for force is the newton, symbol “N”.
  • SI unit for torque (the rotational force) is the N·m (Newton-meter) and the N·cm (Newton-centimeter).

Although the SI unit is widely accepted and used as the standard unit of force in scientific and engineering applications worldwide, following units are used in specific regions or industries: kgf (kilogram-force), lbf (pound-force), kgf·m(kilogram-force meter), lbf·in (pound-force inch) etc.  Here is a unit converter for converting those units of force.
