FAQ

What is the conversion factor from pdl to tnf (US)?
1 pdl equals 1.554048e-5 tnf (US). To convert, multiply the value in poundals by 1.554048e-5.
How do I convert 1 pdl to tnf (US)?
1 pdl = 1.55405e-5 tnf (US). For any value, multiply by 1.554048e-5.
How do I convert tnf (US) back to pdl?
Divide by the same factor — or equivalently, multiply by 64348.1. So 1 tnf (US) = 64348.1 pdl.
When would I need to convert poundal to US short ton-force?
Force conversions between pdl 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).
