Formula
tnf (US) = mN × 1.124045e-7
Multiply any value in millinewtons by 1.124045e-7 to obtain the value in US short tons-force.
Worked example
Convert 1.00000e+6 mN to tnf (US).
- 01Start with 1.00000e+6 mN.
- 02Multiply by the conversion factor: 1.00000e+6 × 1.124045e-7 = 0.112404 tnf (US).
Result1.00000e+6 mN = 0.112404 tnf (US)

FAQ
What is the conversion factor from mN to tnf (US)?
1 mN equals 1.124045e-7 tnf (US). To convert, multiply the value in millinewtons by 1.124045e-7.
How do I convert 1 mN to tnf (US)?
1 mN = 1.12404e-7 tnf (US). For any value, multiply by 1.124045e-7.
How do I convert tnf (US) back to mN?
Divide by the same factor — or equivalently, multiply by 8896443. So 1 tnf (US) = 8.89644e+6 mN.
When would I need to convert millinewton to US short ton-force?
Force conversions between mN 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).
