How to convert kilonewtons to tonnes-force
tf = kN × 0.1019716213Because one tonne-force equals 9.80665 kilonewtons, you can also divide: tf = kN ÷ 9.80665.
A kilonewton is smaller than a tonne-force: it takes 9.80665 kilonewtons to make one tonne-force.

About the units
Kilonewton (kN)
One thousand newtons; used for structural loads, anchor ratings and climbing gear. One kilonewton equals 1,000 newtons (N).
Tonne-force (tf)
The tonne-force (tf) is a unit of force. One tonne-force equals 9,806.65 newtons (N).
Frequently asked questions
How many tonnes-force are in one kilonewton?
There are 0.1019716213 tonnes-force in one kilonewton, and this value is exact by definition.
How do I convert kilonewtons to tonnes-force?
Multiply the number of kilonewtons by 0.1019716213. For example, 10 kN × 0.1019716213 = 1.019716213 tf.
How many kilonewtons are in one tonne-force?
One tonne-force equals 9.80665 kilonewtons. That is the reverse factor, 1 ÷ 0.1019716213.
What is 10 kilonewtons in tonnes-force?
10 kN = 1.019716213 tf.
Is this kN to tf converter accurate?
Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
