Overview
Convert between newtons (N), kilogram-force (kgf), pound-force (lbf), dynes, and more. Used in physics, engineering, and everyday load calculations.
Formula
1 N = 1 kg·m/s² 1 kgf = 9.80665 N 1 N = 0.101972 kgf 1 lbf = 4.44822 N 1 N = 0.224809 lbf 1 dyne = 10⁻⁵ N 1 kN = 1000 N

Tips
- ✔On Earth's surface, gravity exerts about 9.81 N (= 1 kgf) on a 1 kg mass.
- ✔kgf is not an SI unit but is still widely used in engineering and daily life.
- ✔1 ton-force (tf) = 1000 kgf = 9806.65 N.
- ✔In structural engineering, loads are typically expressed in kN (kilonewtons).
FAQ
Q. What is the difference between newtons and kilogram-force?
The newton (N) is the SI unit of force: the force needed to accelerate 1 kg at 1 m/s². kgf is the force exerted by 1 kg under standard gravity (9.80665 m/s²), so 1 kgf = 9.80665 N.
Q. What is the difference between mass (kg) and weight (kgf)?
Mass is the amount of matter in an object, while weight is the gravitational force on it. A 1 kg mass weighs 9.81 N (1 kgf) on Earth but only about 1.63 N on the Moon.
Q. Where are dynes used?
The dyne is the CGS unit of force, mainly used in scientific literature and fields like surface tension measurement. 1 dyne = 10⁻⁵ N.
