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