Formula

Formula
reyn = kg/(m·s) × 0.0001450377

Multiply any value in kilograms per metre-second by 0.0001450377 to obtain the value in reynolds (lbf·s/in²).

Worked example

Convert 10000 kg/(m·s) to reyn.

  1. 01Start with 10000 kg/(m·s).
  2. 02Multiply by the conversion factor: 10000 × 0.0001450377 = 1.45038 reyn.
Result10000 kg/(m·s) = 1.45038 reyn

FAQ

What is the conversion factor from kg/(m·s) to reyn?
1 kg/(m·s) equals 0.0001450377 reyn. To convert, multiply the value in kilograms per metre-second by 0.0001450377.
How do I convert 1 kg/(m·s) to reyn?
1 kg/(m·s) = 0.000145038 reyn. For any value, multiply by 0.0001450377.
How do I convert reyn back to kg/(m·s)?
Divide by the same factor — or equivalently, multiply by 6894.757. So 1 reyn = 6894.76 kg/(m·s).
When would I need to convert kilogram per metre-second to reynolds (lbf·s/in²)?
Dynamic viscosity conversions between kg/(m·s) 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).
