Formula

Formula
N·s/m² = lb/(ft·s) × 1.488164

Multiply any value in pounds per foot-second by 1.488164 to obtain the value in newton-seconds per square metre.

Worked example

Convert 1 lb/(ft·s) to N·s/m².

  1. 01Start with 1 lb/(ft·s).
  2. 02Multiply by the conversion factor: 1 × 1.488164 = 1.48816 N·s/m².
Result1 lb/(ft·s) = 1.48816 N·s/m²

FAQ

What is the conversion factor from lb/(ft·s) to N·s/m²?
1 lb/(ft·s) equals 1.488164 N·s/m². To convert, multiply the value in pounds per foot-second by 1.488164.
How do I convert 1 lb/(ft·s) to N·s/m²?
1 lb/(ft·s) = 1.48816 N·s/m². For any value, multiply by 1.488164.
How do I convert N·s/m² back to lb/(ft·s)?
Divide by the same factor — or equivalently, multiply by 0.671969. So 1 N·s/m² = 0.671969 lb/(ft·s).
When would I need to convert pound per foot-second to newton-second per square metre?
Dynamic viscosity conversions between lb/(ft·s) and N·s/m² 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).
