FAQ
What is the conversion factor from ozf to tnf (US)?
1 ozf equals 3.125e-5 tnf (US). To convert, multiply the value in ounces-force by 3.125e-5.
How do I convert 1 ozf to tnf (US)?
1 ozf = 3.125e-5 tnf (US). For any value, multiply by 3.125e-5.
How do I convert tnf (US) back to ozf?
Divide by the same factor — or equivalently, multiply by 32000. So 1 tnf (US) = 32000 ozf.
When would I need to convert ounce-force to US short ton-force?
Force conversions between ozf 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).
