Convert kg to newtons

Please provide values below to convert kilogram-force [kgf] to newton [N], or vice versa.



Definition: A kilogram-force (symbol: kgf) is a unit of force in the gravitational metric system. It is defined as the magnitude of force applied to one kilogram of mass under the condition of standard gravity (9.80665 m/s2). One kilogram-force is therefore equal to 9.80665 N.

History/origin: Although the kilogram-force was used in some imprecise measurements of force in the past, it was not until 1901 when the General Conference of Weights and Measures adopted a standard acceleration due to gravity of 9.80665 m/s2 that the kilogram-force became a well-defined measurement of force. Prior to the adoption of the International System of Units (SI) in 1960, the kilogram force was used around the world in the space programs of countries like China, Germany, and Russia.

Current use: The kilogram-force has largely been replaced by the Newton, the SI derived unit of force, but is still used in China, and in some cases, by the European Space Agency, an intergovernmental agency consisting of 22 member states.


Definition: The newton (symbol: N) is the SI (International System of Units) derived unit of force. It is defined as 1 kilogram·meter/second2.

History/origin: The unit newton is named after Isaac Newton for his contribution to classical mechanics – particularly his second law of motion, which states that the rate of change of momentum of a body is directly proportional to the applied force, and that this change in momentum occurs in the direction of the applied force.

Current use: As an SI derived unit of force, the newton is the preferred unit of force, and is widely used in scientific contexts, particularly in physics. In everyday use, units such as the pound-force are sometimes used in place of newtons in countries like the United States.

How to Convert Kilogram-force to Newton

1 kgf = 9.80665 N
1 N = 0.1019716213 kgf

Example: convert 15 kgf to N:
15 kgf = 15 × 9.80665 N = 147.09975 N
