FAQ
What is the conversion factor from pdl to lbf?
1 pdl equals 0.03108095 lbf. To convert, multiply the value in poundals by 0.03108095.
How do I convert 1 pdl to lbf?
1 pdl = 0.031081 lbf. For any value, multiply by 0.03108095.
How do I convert lbf back to pdl?
Divide by the same factor — or equivalently, multiply by 32.17405. So 1 lbf = 32.174 pdl.
When would I need to convert poundal to pound-force?
Force conversions between pdl and lbf 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).
