Kilogram-force to Newton Formula & Unit Definitions
By international convention established at the 3rd General Conference on Weights and Measures (CGPM) in 1901, standard gravitational acceleration g₀ was defined as exactly 9.80665 m/s². Because 1 kilogram-force (kgf or kilopond kp) is the gravitational force exerted on a 1-kilogram mass under this standard acceleration, 1 kgf equals exactly 9.80665 newtons. To convert any force in kilograms-force to newtons, simply multiply by 9.80665.
Quick Estimation: Quick mental shortcut: To convert kilograms-force to newtons mentally, multiply the value by 10 and subtract 2%. For example, 50 kgf × 10 = 500 N; subtracting 2% (10 N) gives 490 N (exact: 490.33 N). For 100 kgf, 100 × 10 - 2% = 980 N (exact: 980.67 N).
Kilogram-force — kgf
Gravitational Metric- Downward force exerted by 1 kg of mass under standard acceleration (9.80665 m/s²)
- Widely known as the kilopond (kp) across European engineering literature and drawings
- Commonly found on hydraulic press gauges, cable hoists, and legacy dynamometers
Newton — N
SI Base Metric- International coherent unit of force derived from mass and acceleration (1 kg·m/s²)
- Completely independent of Earth's local gravitational pull or orbital location
- Universal metric standard for structural mechanics, aerospace dynamics, and physics
Frequently Asked Questions
Q.How many newtons are in a kilogram-force?
There are exactly 9.80665 newtons in one kilogram-force (1 kgf = 9.80665 N).
Q.What is the reverse conversion from newtons to kilograms-force?
To convert back, use the Newtons to Kilograms-Force Converter where 1 N equals approximately 0.101972 kgf.
Q.How many newtons is 100 kgf?
100 kilograms-force equals exactly 980.665 newtons.
Q.What formula converts kgf to N?
