Convert between kilograms-force (kgf) and newtons (N) in both directions. Enter a value in the Kilograms-force field to get the equivalent in newtons, or enter Newtons to convert back to kgf. The result uses the standard gravitational constant of 9.80665 m/s² for precise force conversion.

A kilogram-force (kgf) is defined as the force exerted by gravity on a mass of 1 kilogram at Earth's surface. Since standard gravity is 9.80665 m/s², one kilogram-force equals exactly 9.80665 newtons. The newton, by contrast, is the SI unit of force defined as the force needed to accelerate a 1 kg mass at 1 m/s².
Multiply the kilogram-force value by 9.80665 to get newtons. For example, 10 kgf × 9.80665 = 98.0665 N. You can also use this calculator by entering your kgf value in the Kilograms-force field and reading the Newtons result directly.
1 newton is equal to approximately 0.10197 kilogram-force (kgf). This is calculated by dividing 1 by the standard gravitational constant: 1 ÷ 9.80665 ≈ 0.10197 kgf.
A kilogram-force (kgf) is a gravitational metric unit of force. It represents the force that standard gravity (9.80665 m/s²) exerts on a mass of one kilogram. While not an SI unit, it was widely used in engineering and space programs before the adoption of the newton as the standard unit of force.
One newton is the force required to accelerate a 1-kilogram mass at a rate of 1 metre per second squared (1 m/s²). In everyday terms, a newton is roughly the force of gravity on a small apple (about 102 grams).
The value 9.80665 m/s² is the internationally adopted standard acceleration of gravity, defined by the General Conference of Weights and Measures in 1901. It represents a standardised reference value used in unit conversion, even though actual gravitational acceleration varies slightly depending on location on Earth.
Yes. To convert newtons to kgf, divide the newton value by 9.80665. For example, 50 N ÷ 9.80665 ≈ 5.0986 kgf. This calculator supports both directions — simply enter your newton value in the Newtons field to get the kgf equivalent.
No. A kilogram (kg) is a unit of mass, while kilogram-force (kgf) is a unit of force. In everyday language, people often say 'kilograms' when referring to weight (which is a force), but scientifically they are distinct. When converting to newtons, we treat the kilogram value as kilogram-force, applying the standard gravity constant.
