Kilograms-force to newtons
Multiply kilograms-force by 9.8067 to get newtons.
20 kgf = 196.133 N
How to convert kilograms-force to newtons
The newton is the SI unit of force — one kg accelerated at one m/s². The kilogram-force is the force of one kilogram under standard gravity, exactly 9.80665 N.
Worked example — 20 kgf: 20 × 9.8067 = 196.133 N.

About kilograms-force and newtons
Kilogram-force (kgf)
1 kgf = 9.8067 NDefinition. The force of one kilogram under standard gravity, exactly 9.80665 N
History and origin
The kilogram-force, also called the kilopond, is the weight of one kilogram under standard gravity, exactly 9.80665 newtons. It was common before the newton became standard.
Current use
Kilograms-force still appear in some engineering and in torque specifications outside the United States.
Source: NIST SP 811, App. B (force). lbf and kgf are exact via the pound/kilogram and standard gravity 9.80665 m/s² (CGPM 1901); SP 811 prints them rounded
Newton (N)
1 N = 0.101972 kgfDefinition. The SI unit of force — one kg accelerated at one m/s²
History and origin
The newton is the SI unit of force, named after Isaac Newton, defined as the force that accelerates one kilogram at one metre per second squared. It replaced a patchwork of older force units.
Current use
Newtons are used in physics and engineering to state loads and forces.
