About the Force Converter
The force converter switches between newtons, kilonewtons, dynes, kilogram-force, gram-force, tonne-force, pound-force, ounce-force, kips and poundals. It converts through the newton, the SI unit of force, using exact standard values such as 1 kgf = 9.80665 N and 1 lbf = 4.448222 N. It is useful in engineering, physics and when reading specifications from different countries.
How to use it
- 1Type the value you want to convert.
- 2Choose the unit you are converting from and the unit you want (for example kgf to newtons).
- 3The result updates as you type; use the swap button to reverse the direction.
- 4Copy or share the result with the buttons below it.
Worked example
50 kgf × 9.80665 = 490.3 N, and 100 lbf = 444.8 N.
How it works
SI unit of force
The Newton (N) is the SI derived unit of force: 1 N = 1 kg·m/s². Key relationships:
- 1 kgf = 9.80665 N (exact, g₀)
- 1 lbf = 4.44822 N
- 1 dyn = 10⁻⁵ N
- 1 kip = 1000 lbf = 4448.22 N
Common use cases
- Converting load ratings between kgf and newtons
- Physics homework
- Reading engineering specifications
Frequently asked questions
A:1 kgf is the gravitational force on 1 kg of mass at standard gravity (9.80665 m/s²) = 9.80665 N.
A:The poundal (pdl) is the FPS unit of force: the force required to accelerate 1 lb by 1 ft/s². 1 pdl ≈ 0.1383 N.
