About the units

Gram-force
The weight of one gram under standard gravity, exactly 0.00980665 newton, seen in key switch and small spring specs.
Newton
The SI unit of force: the force that gives a mass of one kilogram an acceleration of one meter per second squared (1 N = 1 kg·m/s²).

Limits and caveats

  • Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).

Questions about this tool

How many newtons are in one gram-force?

1 gf = 0.00980665 N exactly.

How do I convert grams-force to newtons?

Use N = gf × 0.00980665. For example, 25 gf = 0.245166 N.

How many grams-force are in one newton?

1 N = 101.972 gf.

What is the difference between a kilogram and a kilogram-force?

The kilogram is a unit of mass, while the kilogram-force is the weight of that mass under standard gravity, exactly 9.80665 newtons. So a 10 kg object presses down with about 98.07 newtons.

Why are climbing ropes and anchors rated in kilonewtons?

The kilonewton is a standard force unit that suits large loads. As a quick estimate, 1 kN is about 102 kilograms-force.
