Kilogram-Force to Newtons Converter

How it is calculated

The kilogram-force is the force with which standard gravity pulls on one kilogram, and standard gravity is defined as 9.80665 m/s². So the conversion is N = kgf × 9.80665. The pounds-force figure uses lbf = kgf × 2.2046226, the number of pounds in a kilogram. Both are shown with two decimals. Negative values are not rejected and convert with the same factors, which may be useful for a force with an opposite direction. This is a pure unit conversion between force units, not a mass conversion, so it does not depend on where on Earth you are.

Common mistakes

• Treating kgf as a mass. A 25 kg object weighs 25 kgf only under standard gravity; the number you enter must already be a force reading.
• Using 10 or 9.8 in place of 9.80665 for precise work; the tool uses the exact standard value.
• Confusing kgf with kilonewton (kN). 1 kN is about 101.97 kgf, not 1 kgf.
• Confusing lbf with lb mass. The pound result here is pounds-force, a unit of force.
• Reading torque specs such as kgf·m as simple force. A torque in kgf·m needs multiplying by 9.80665 for N·m, but the lever length is part of the unit.
