Convert a mass in kilograms to weight in newtons, the force that mass exerts under Earth gravity. Enter the kilograms and get the force in newtons and in pounds-force. Useful for physics homework and quick engineering checks where mass and force get mixed up.
How this is calculated
Weight is mass times gravitational acceleration. This uses standard gravity, g = 9.80665 m/s^2, the value fixed by the CGPM, so newtons = kg * 9.80665. Pounds-force use the exact definition 1 lbf = 4.4482216152605 N.
How to use
- Enter the mass in kilograms.
- Read the weight in newtons.
- Use the pounds-force value for imperial work.
Examples
- 10 kg:
10 kg = 98.07 N - 75 kg:
75 kg = 735.50 N
FAQ
- Why is a kilogram not the same as a newton?
- A kilogram is a unit of mass, while a newton is a unit of force. On Earth, one kilogram of mass weighs about 9.81 newtons because gravity pulls on it.
- What gravity value is used?
- Standard gravity, 9.80665 m/s^2. This is the internationally agreed average. Actual gravity varies slightly with location and altitude.
- How do I get pounds-force?
- The tool divides the newton value by 4.4482216152605, the exact number of newtons in one pound-force.
