Factor1 kN = 0.1124045 tnf (US)
Converter
kN
Accepts numbers or expressions, e.g. 150 + 14.7
Result
tnf (US)
Rendered to 6 significant figures.
Formula
Formula
tnf (US) = kN × 0.1124045
Multiply any value in kilonewtons by 0.1124045 to obtain the value in US short tons-force.
Worked example
Convert 1000 kN to tnf (US).
- 01Start with 1000 kN.
- 02Multiply by the conversion factor: 1000 × 0.1124045 = 112.404 tnf (US).
Result1000 kN = 112.404 tnf (US)

FAQ
What is the conversion factor from kN to tnf (US)?
1 kN equals 0.1124045 tnf (US). To convert, multiply the value in kilonewtons by 0.1124045.
How do I convert 1 kN to tnf (US)?
1 kN = 0.112404 tnf (US). For any value, multiply by 0.1124045.
How do I convert tnf (US) back to kN?
Divide by the same factor — or equivalently, multiply by 8.896443. So 1 tnf (US) = 8.89644 kN.
When would I need to convert kilonewton to US short ton-force?
Force conversions between kN and tnf (US) are needed in structural analysis, mechanical equipment design, lifting and rigging calculations, and load specification. Newtons and kilonewtons are standard in SI-based structural codes; pound-force and kips are common in US codes and vendor datasheets.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
