Formula

Formula
lb/(ft·hr) = N·s/m² × 2419.088

Multiply any value in newton-seconds per square metre by 2419.088 to obtain the value in pounds per foot-hour.

Worked example

Convert 1 N·s/m² to lb/(ft·hr).

  1. 01Start with 1 N·s/m².
  2. 02Multiply by the conversion factor: 1 × 2419.088 = 2419.09 lb/(ft·hr).
Result1 N·s/m² = 2419.09 lb/(ft·hr)

FAQ

What is the conversion factor from N·s/m² to lb/(ft·hr)?
1 N·s/m² equals 2419.088 lb/(ft·hr). To convert, multiply the value in newton-seconds per square metre by 2419.088.
How do I convert 1 N·s/m² to lb/(ft·hr)?
1 N·s/m² = 2419.09 lb/(ft·hr). For any value, multiply by 2419.088.
How do I convert lb/(ft·hr) back to N·s/m²?
Divide by the same factor — or equivalently, multiply by 0.0004133789. So 1 lb/(ft·hr) = 0.000413379 N·s/m².
When would I need to convert newton-second per square metre to pound per foot-hour?
Dynamic viscosity conversions between N·s/m² and lb/(ft·hr) 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).
