mPa·stokg/(m·s)
Convert millipascal-seconds (mPa·s) to kilograms per metre-second (kg/(m·s)).
Factor1 mPa·s = 0.001 kg/(m·s)
Converter
mPa·s
Accepts numbers or expressions, e.g. 150 + 14.7
Result
kg/(m·s)
Rendered to 6 significant figures.
Formula
Formula
kg/(m·s) = mPa·s × 0.001
Multiply any value in millipascal-seconds by 0.001 to obtain the value in kilograms per metre-second.
Worked example
Convert 1000 mPa·s to kg/(m·s).
- 01Start with 1000 mPa·s.
- 02Multiply by the conversion factor: 1000 × 0.001 = 1 kg/(m·s).
Result1000 mPa·s = 1 kg/(m·s)

FAQ
What is the conversion factor from mPa·s to kg/(m·s)?
1 mPa·s equals 0.001 kg/(m·s). To convert, multiply the value in millipascal-seconds by 0.001.
How do I convert 1 mPa·s to kg/(m·s)?
1 mPa·s = 0.001 kg/(m·s). For any value, multiply by 0.001.
How do I convert kg/(m·s) back to mPa·s?
Divide by the same factor — or equivalently, multiply by 1000. So 1 kg/(m·s) = 1000 mPa·s.
When would I need to convert millipascal-second to kilogram per metre-second?
Dynamic viscosity conversions between mPa·s and kg/(m·s) 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).
