Force Converter

Enter a force in any common unit and see it in all the others instantly: millinewton (mN), newton (N), kilonewton (kN), meganewton (MN), dyne (dyn), gram-force (gf), kilogram-force (kgf), metric ton-force (tf), ounce-force (ozf) and pound-force (lbf). The value is converted to newtons internally and then to every unit, so conversions are exact. Handy for physics and engineering (N, kN), mechanics and weight-as-force (kgf, lbf), springs and small loads (gf, ozf, dyn) and structural work (tf, MN). Everything is computed locally in your browser.

Frequently asked questions

What is the difference between kgf and N?
A kilogram-force (kgf) is the force gravity exerts on a 1 kg mass at standard gravity: 1 kgf = 9.80665 N exactly. So a 1 kg object weighs about 9.81 N. kgf is a gravitational unit; the newton is the SI unit.
How many newtons is one pound-force?
1 lbf = 4.4482216152605 N (defined via standard gravity acting on the avoirdupois pound). Conversely 1 N ≈ 0.2248 lbf, and 1 ozf = lbf/16 ≈ 0.2780 N.
What is a dyne?
The dyne is the CGS unit of force: 1 dyn = 1 g·cm/s² = 1e-5 N. It shows up in older physics texts and surface-tension values (dyn/cm). One newton equals 100,000 dynes.
Is force the same as mass or weight?
No. Mass (kg) is how much matter an object has; force (N) is a push or pull. Weight is the force of gravity on a mass — that's why kgf and lbf exist as "force" versions of mass units, tied to standard gravity 9.80665 m/s².
