Formula

Formula
cP = lb/(ft·hr) × 0.4133789

Multiply any value in pounds per foot-hour by 0.4133789 to obtain the value in centipoise.

Worked example

Convert 1000 lb/(ft·hr) to cP.

  1. 01Start with 1000 lb/(ft·hr).
  2. 02Multiply by the conversion factor: 1000 × 0.4133789 = 413.379 cP.
Result1000 lb/(ft·hr) = 413.379 cP

FAQ

What is the conversion factor from lb/(ft·hr) to cP?
1 lb/(ft·hr) equals 0.4133789 cP. To convert, multiply the value in pounds per foot-hour by 0.4133789.
How do I convert 1 lb/(ft·hr) to cP?
1 lb/(ft·hr) = 0.413379 cP. For any value, multiply by 0.4133789.
How do I convert cP back to lb/(ft·hr)?
Divide by the same factor — or equivalently, multiply by 2.419088. So 1 cP = 2.41909 lb/(ft·hr).
When would I need to convert pound per foot-hour to centipoise?
Dynamic viscosity conversions between lb/(ft·hr) and cP 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).
