Convert Poise to Pascal-seconds
1 poise (P) equals 0.1 pascal-seconds (Pa·s).
1 P = 0.1 Pa·s

How to Convert Poise to Pascal-second
- 1 P = 0.1 Pa·s
- 1 Pa·s = 10 P
- Example: convert 15 P to Pa·s: 15 P = 15 × 0.1 Pa·s = 1.5 Pa·s
Formula
Pa·s = P ÷ 10
Derivation from SI units:
- 1 P = 1 dyn·s/cm² = 0.1 Pa·s
- 1 Pa·s = 1 N·s/m² = 1 kg·m⁻¹·s⁻¹
Both units are defined exactly, so the factor is exact. Poise definition: poise; Pascal-second definition: pascal-second.
Worked examples
- A reading of 1 P converts to 0.1 Pa·s.
1 P × 0.1 = 0.1 Pa·s - A value of 10 P is 1 Pa·s.
10 P × 0.1 = 1 Pa·s

Where it's used
Poise are used for older physics and rheology literature, while pascal-seconds appear in engineering fluid-flow and Reynolds-number calculations. Both measure dynamic (absolute) viscosity, so the conversion is a fixed factor.
Poise to other dynamic viscosity units
| Conversion | 1 P equals |
|---|---|
| poise to pascal-second | 0.1 Pa·s |
| poise to millipascal-second | 100 mPa·s |
| poise to centipoise | 100 cP |
| poise to pound-force second per square foot | 0.002088543423 lbf·s/ft² |
| poise to pound per foot-second | 0.06719689751 lb/(ft·s) |
Frequently asked questions
How many pascal-seconds are in 1 poise?
1 P = 0.1 Pa·s.
How do I convert poise to pascal-seconds?
Multiply the value in P by 0.1, or divide it by 10. For example, 15 P × 0.1 = 1.5 Pa·s.
Is the P to Pa·s conversion exact?
Yes. Both units are defined exactly, and 1 P is exactly 0.1 Pa·s.
