maratoolHow to convert centipoise to Pa·s (dynamic viscosity)
Type a viscosity — read Pa·s, mPa·s, poise, cP, or lbf·s/ft² instantly.
Pump sizing, lubricant specs, and CFD input files all disagree on viscosity units. The Dynamic Viscosity Converter converts CGS, SI, and US units through the pascal-second.
How it works
- Pick units — "Centipoise (cP)" to "Pascal-second (Pa·s)", or any other pair.
- Type a value — the result updates as you type, with swap and copy.
- Copy — one click, with "Copied!" feedback.
Dynamic viscosity conversion factors
Every unit converts through the pascal-second (the base unit). To convert A → B, multiply by A's factor and divide by B's:
| Unit | = this many pascal-seconds |
|---|---|
| Pascal-second (Pa·s) | 1 |
| Millipascal-second (mPa·s) | 0.001 |
| Poise (P) | 0.1 |
| Centipoise (cP) | 0.001 |
| Pound per foot-second (lb/(ft·s)) | 1.48816394357 |
| Pound-force second per square foot (lbf·s/ft²) | 47.880258980336 |
| Kilogram per meter-hour (kg/(m·h)) | 0.000277777778 |
When you need it
Since 1 cP = 1 mPa·s exactly, the cP→Pa·s conversion is just a factor of 1,000. The US unit lbf·s/ft² is much larger (47.88 Pa·s) and shows up in older hydraulics texts. Kinematic viscosity (viscosity ÷ density) has its own units — see the Kinematic Viscosity Converter.
Sources & methodology
Conversion factors follow NIST Special Publication 811; exact-by-definition factors are marked in the tool itself. All math runs client-side in your browser — nothing is uploaded.
