Unit Conversion

Convert force units: newton, kilonewton, kilopond, and pound-force

Force is measured in newton (N), the SI unit, as well as in kilonewton (kN) and meganewton (MN) for larger amounts of force. Also available are kilogram-force (kgf, colloquially kilopond) based on Earth's gravity, pound-force (lbf), common in the US/UK, and the small CGS unit dyne.

Key conversion factors:

  • 1 kilonewton (kN) = 1,000 newton (N)
  • 1 meganewton (MN) = 1,000,000 newton – order of magnitude of engine thrust
  • 1 kilogram-force (kgf) = 9.807 newton – weight force of 1 kg in Earth's gravitational field
  • 1 pound-force (lbf) = 4.448 newton – US unit of force
  • 1 dyne (dyn) = 10^-5 newton – CGS unit for very small forces

Applications:

  • Structural engineering & construction: load-bearing capacity and tensile strength of components in kilonewton
  • Automotive engineering: traction and drive force of vehicles in newton
  • Aerospace: engine thrust in kilo- and meganewton
  • Physics: gravitational, spring, and friction forces in newton

The force converter supports technical comparisons, structural calculations, and evaluating designs. For torque (force times lever arm), use the torque converter.

Frequently asked questions about converting force

1 kilogram-force (kgf, also called kilopond) equals 9.80665 newton – the weight force that 1 kg of mass produces in Earth's gravitational field. Kilogram-force is still used colloquially in some engineering contexts, but it is not an SI unit.

1 pound-force (lbf) equals 4.448 newton. Pound-force is the unit of force commonly used in the US, while newton (N) is the international SI unit for force.

1 dyne equals 10^-5 newton, i.e. one hundred-thousandth of a newton. Dyne comes from the older CGS system of units and today is mainly still used in older physics texts or for very small forces at the microscopic scale.
