Force converter
F(N) = m(kg) × g₀
Convert a force between newtons, millinewtons, kilonewtons, dynes, kilograms-force and pounds-force. The mass-derived “force” units (kgf, lbf) rely on the standard acceleration of gravity g₀ = 9.80665 m/s², fixed by convention: their factors are therefore exact, not measured.

Method & formulasF(N) = m(kg) × g₀
F(N) = m(kg) × g₀
g₀ = 9.80665 m/s² (exactly)
The kilogram-force and pound-force are not masses: they are the forces exerted by one kilogram and one pound respectively under standard gravity. That acceleration is a conventional value fixed in 1901, not a local measurement. Real gravity varies by about 0.5 % between the equator and the poles.

Why the dyne survivesThe dyne (10⁻⁵ N) is the CGS unit of force.
The dyne (10⁻⁵ N) is the CGS unit of force. It remains common in surface science, where surface tensions are quoted in dyn/cm, a value in dyn/cm is numerically equal to the same value in mN/m, which explains why both notations coexist in the literature.
