Force Converter

Your inputs

Kilograms-force and tonnes-force assume standard Earth gravity (9.80665 m/s2). On the Moon the same mass would weigh about a sixth as much force.

Force Converter guide

Convert newtons and kilonewtons to pounds-force, kilograms-force, dynes and tonnes-force — for physics, engineering loads, lifting and thrust figures.

How to use this tool

  1. Enter the value you want to convert.
  2. Choose the source and destination units. Use Swap to reverse them.
  3. Compare the live equivalents, then copy a result or download the table as CSV.

A worked example

A 1 kg mass resting on Earth weighs 9.81 newtons — exactly 1 kilogram-force by definition.

What you can do with this tool

How it works

Result = input × source-unit factor ÷ destination-unit factor. All factors are relative to the same base unit; intermediate values are not rounded.

Frequently asked questions

Which unit definitions are used?

Newtons, Kilonewtons, Pounds-force, Kilograms-force, Dynes, Tonnes-force. Read the labels carefully: regional or decimal/binary variants are separate choices.

Is a kilogram a unit of force?

Strictly, no: the kilogram measures mass. Kilograms-force is the weight of that mass under standard gravity, kept here because scales, ropes and datasheets still quote it.
