Formula
Formula
reyn = lb/(ft·hr) × 5.995554e-8
Multiply any value in pounds per foot-hour by 5.995554e-8 to obtain the value in reynolds (lbf·s/in²).
Worked example
Convert 1000 lb/(ft·hr) to reyn.
- 01Start with 1000 lb/(ft·hr).
- 02Multiply by the conversion factor: 1000 × 5.995554e-8 = 5.99555e-5 reyn.
Result1000 lb/(ft·hr) = 5.99555e-5 reyn

FAQ
What is the conversion factor from lb/(ft·hr) to reyn?
1 lb/(ft·hr) equals 5.995554e-8 reyn. To convert, multiply the value in pounds per foot-hour by 5.995554e-8.
How do I convert 1 lb/(ft·hr) to reyn?
1 lb/(ft·hr) = 5.99555e-8 reyn. For any value, multiply by 5.995554e-8.
How do I convert reyn back to lb/(ft·hr)?
Divide by the same factor — or equivalently, multiply by 1.667903e+7. So 1 reyn = 1.6679e+7 lb/(ft·hr).
When would I need to convert pound per foot-hour to reynolds (lbf·s/in²)?
Dynamic viscosity conversions between lb/(ft·hr) and reyn are common in fluid characterisation, pump and control valve sizing, pipeline pressure-drop calculations, and lubrication engineering. Centipoise (cP) and mPa·s are the most widely used units in process datasheets; Pa·s is required for most simulation tools.
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).
