šļø Weight Calculator
Weight is a force: your mass times the pull of gravity. Enter a mass in kilograms and this calculator applies W = m Ć g with g = 9.80665 m/sĀ² to give the weight in newtons.
It also converts to pound-force, the imperial unit of weight, so engineers and students can work in either system.
How to use this calculator
Enter a mass in kilograms. The calculator applies W = m times g to give the weight force in newtons and pound-force.
- Type the Mass in kilograms.
- Read the weight in newtons instantly.
- Use the pound-force line for the imperial equivalent.
- Change the input to convert any other mass.
Frequently asked questions
What does the Weight Calculator compute?
It turns mass into weight force using W = m times g, with standard gravity g = 9.80665 meters per second squared. Results are shown in newtons and in pound-force.
What is the difference between mass and weight?
Mass in kilograms is how much matter something contains. Weight in newtons is the force gravity exerts on that mass. A scale reads weight but is calibrated to display mass assuming Earth gravity.
Can you give a worked example?
A 70 kilogram mass weighs 686.47 newtons, which is 154.32 pound-force.
Does gravity vary?
Slightly, by latitude and altitude, but 9.80665 is the agreed standard value and is used here for consistency.
