This converter turns kilograms-force into kilonewtons instantly, using the exact factor 1 kilogram-force = 0.00980665 kilonewtons. Type any number and the result updates as you go — nothing is sent to a server, so the arithmetic happens entirely in your browser.
The force gravity exerts on one kilogram — a legacy metric unit. Used in structural engineering and climbing-gear ratings.
Because the relationship is a simple proportion, one multiplication does the whole job. The table further down gives pre-computed values for the amounts people look up most often, and the result panel also reports the reverse conversion so you can check the figure both ways.
The formula
kilograms-force- The amount you are converting, measured in kilograms-force
0.00980665- The exact number of kilonewtons in one kilogram-force
kilonewtons- The converted result
How it works, step by step
- Enter the number of kilograms-force you want to convert.
- The value is multiplied by 0.00980665, the exact conversion factor.
- The result is displayed in kilonewtons, rounded for readability.
- The unrounded value and the reverse conversion appear underneath so you can verify it.
Worked examples
Converting 5 kilograms-force
Multiply 5 by 0.00980665. That gives 0.049033 kilonewtons. A quick sanity check: one kilogram-force is smaller than one kilonewton, so the number should get smaller — and it does.
Converting 72 kilograms-force
72 × 0.00980665 = 0.706079 kilonewtons. Working backwards, 0.706079 ÷ 0.00980665 returns 72 kilograms-force, which confirms the factor is applied the right way round.
How to read your score
Frequently asked questions
How many kilonewtons are in one kilogram-force?
Exactly 0.00980665. Every conversion on this page is that single number multiplied by your input, so the result carries no rounding error beyond what is shown.
What is the formula to convert kilograms-force to kilonewtons?
Kilonewtons = kilograms-force × 0.00980665. To reverse it, divide instead: kilograms-force = kilonewtons ÷ 0.00980665, which is the same as multiplying by 101.9716213.
Is the kilogram-force bigger than the kilonewton?
No. One kilogram-force is only 0.00980665 of a kilonewton, so the kilonewton is the larger unit.
Why does my answer differ slightly from other kilogram-force to kilonewtons converters?
Most differences come from rounding the factor too early. This tool keeps full double precision through the calculation and only rounds at the final display step, and it also shows the unrounded value so you can see exactly where any difference appears.
