FAQ

What is the conversion factor from gf to tnf (UK)?
1 gf equals 9.842065e-7 tnf (UK). To convert, multiply the value in grams-force by 9.842065e-7.
How do I convert 1 gf to tnf (UK)?
1 gf = 9.84207e-7 tnf (UK). For any value, multiply by 9.842065e-7.
How do I convert tnf (UK) back to gf?
Divide by the same factor — or equivalently, multiply by 1016047. So 1 tnf (UK) = 1.01605e+6 gf.
When would I need to convert gram-force to UK long ton-force?
Force conversions between gf and tnf (UK) 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).
