FAQ

What is the conversion factor from tnf (UK) to kN?
1 tnf (UK) equals 9.964016 kN. To convert, multiply the value in UK long tons-force by 9.964016.
How do I convert 1 tnf (UK) to kN?
1 tnf (UK) = 9.96402 kN. For any value, multiply by 9.964016.
How do I convert kN back to tnf (UK)?
Divide by the same factor — or equivalently, multiply by 0.1003611. So 1 kN = 0.100361 tnf (UK).
When would I need to convert UK long ton-force to kilonewton?
Force conversions between tnf (UK) and kN 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).
