Convert Centipoise to Pascal-seconds
1 centipoise (cP) equals 0.001 pascal-seconds (Pa·s).
1 cP = 0.001 Pa·s

How to Convert Centipoise to Pascal-second
- 1 cP = 0.001 Pa·s
- 1 Pa·s = 1000 cP
- Example: convert 100 cP to Pa·s: 100 cP = 100 × 0.001 Pa·s = 0.1 Pa·s
Formula
Pa·s = cP ÷ 1000
Derivation from SI units:
- 1 cP = 0.01 P = 10⁻³ 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. Centipoise definition: centipoise; Pascal-second definition: pascal-second.
Worked examples
- Water at 20 °C, about 1 cP, is 0.001 Pa·s.
1 cP × 0.001 = 0.001 Pa·s - A 500 cP resin is 0.5 Pa·s.
500 cP × 0.001 = 0.5 Pa·s

Frequently asked questions
How many Pa·s is 1 cP?
Exactly 0.001 Pa·s.
How many pascal-seconds are in 1 centipoise?
1 cP = 0.001 Pa·s.
How do I convert centipoise to pascal-seconds?
Multiply the value in cP by 0.001, or divide it by 1000. For example, 100 cP × 0.001 = 0.1 Pa·s.
Is the cP to Pa·s conversion exact?
Yes. Both units are defined exactly, and 1 cP is exactly 0.001 Pa·s.
