Force Converter

1 kilogram-force (kgf) equals exactly 9.80665 newtons. This is the force exerted by a 1 kg mass under standard gravity. A 70 kg person exerts approximately 686.5 N of force on the ground.

To convert newtons to pound-force, divide by 4.4482. For example, 100 N equals approximately 22.48 lbf. This conversion is common when comparing US and international structural specifications.

A kilogram (kg) is a unit of mass, while kilogram-force (kgf) is a unit of force. 1 kgf is the gravitational force on 1 kg at sea level (9.80665 N). Confusing mass and force is a common error in engineering - always check which unit a specification requires.

1 metric ton-force (1000 kgf) equals approximately 9.807 kilonewtons. Kilonewtons are used in structural engineering for beam loads, bridge ratings and foundation design.

A dyne is the CGS unit of force, equal to 0.00001 newtons (10 micronewtons). Dynes are used in surface tension measurements (dynes/cm), fluid dynamics and some older scientific literature. Most modern work uses newtons.
