About the units
- Metric ton-force
- The weight of one metric ton (1000 kg) under standard gravity, exactly 9806.65 newtons, used for press and crane capacity.
- Kilonewton
- Exactly 1000 newtons, the usual unit for structural loads, anchor ratings and climbing gear.
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 kilonewtons are in one metric ton-force?
1 tf = 9.80665 kN exactly.
How do I convert metric tons-force to kilonewtons?
Use kN = tf × 9.80665. For example, 25 tf = 245.166 kN.
How many metric tons-force are in one kilonewton?
1 kN = 0.101972 tf.
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.
