FAQ
What is the conversion factor from pdl to mN?
1 pdl equals 138.255 mN. To convert, multiply the value in poundals by 138.255.
How do I convert 1 pdl to mN?
1 pdl = 138.255 mN. For any value, multiply by 138.255.
How do I convert mN back to pdl?
Divide by the same factor — or equivalently, multiply by 0.007233014. So 1 mN = 0.00723301 pdl.
When would I need to convert poundal to millinewton?
Force conversions between pdl and mN 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).
