How to use it
- Type the value in the newtons box.
- Read the result in millinewtons as you type, and pick the precision you need.
- Swap the direction to convert back, or copy the result.
How it is calculated
mN = N × 1,000
Multiply the value in newtons by 1,000 to get millinewtons.
Example
To convert 25 N to millinewtons: 25 × 1,000 = 25,000 mN.

About the units
- Newton
- The SI unit of force: the force that gives a mass of one kilogram an acceleration of one meter per second squared (1 N = 1 kg·m/s²).
- Millinewton
- One thousandth of a newton, used for small forces such as button presses and precision sensors.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many millinewtons are in one newton?
1 N = 1,000 mN exactly.
How do I convert newtons to millinewtons?
Use mN = N × 1,000. For example, 25 N = 25,000 mN.
How many newtons are in one millinewton?
1 mN = 0.001 N.
What is the difference between a kilogram and a kilogram-force?
The kilogram is a unit of mass, while the kilogram-force is the weight of that mass under standard gravity, exactly 9.80665 newtons. So a 10 kg object presses down with about 98.07 newtons.
Why are climbing ropes and anchors rated in kilonewtons?
The kilonewton is a standard force unit that suits large loads. As a quick estimate, 1 kN is about 102 kilograms-force.
