About this tool
Convert a force value between eight units, fully in your browser with nothing uploaded. Choose the From and To units, enter a value, and the result updates live; the ⇄ button swaps them.
Force is referenced to the SI base unit newton (N): the value is multiplied by the From factor to get newtons, then divided by the To factor. Gravitational units use standard gravity g = 9.80665 m/s², so 1 kgf = 9.80665 N and 1 metric ton-force = 9806.65 N. One pound-force is 4.4482216 N.
Handy for statics, engineering and physics homework. For example 1 kgf ≈ 9.807 N, and 1 lbf ≈ 4.448 N.
Frequently asked questions
What base unit is used?
The newton (N). Every unit has an exact factor to newtons; conversions are value × from-factor ÷ to-factor.
What value of gravity does kilogram-force use?
Standard gravity, g = 9.80665 m/s². So 1 kgf = 9.80665 N and 1 metric ton-force = 9806.65 N.
How big is a dyne?
Very small — 1 dyne = 1e-5 N, the CGS unit of force. It takes 100,000 dyne to make one newton.
How many newtons is a pound-force?
One pound-force is 4.4482216 N, and one ounce-force (1/16 lbf) is about 0.278 N.
