FAQ

What is the conversion factor from tnf (UK) to tnf (US)?
1 tnf (UK) equals 1.12 tnf (US). To convert, multiply the value in UK long tons-force by 1.12.
How do I convert 1 tnf (UK) to tnf (US)?
1 tnf (UK) = 1.12 tnf (US). For any value, multiply by 1.12.
How do I convert tnf (US) back to tnf (UK)?
Divide by the same factor — or equivalently, multiply by 0.8928571. So 1 tnf (US) = 0.892857 tnf (UK).
When would I need to convert UK long ton-force to US short ton-force?
Force conversions between tnf (UK) 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).
