Dynamic viscosity

P to cP conversion

Convert poise (P) to centipoise (cP). Dynamic viscosity is a fluid's resistance to shear — the property that sets the Reynolds number and the friction factor.

1 P = 100 cP

Formula

To convert poise to centipoise, multiply the P value by 100. To go the other way, divide by 100 (or multiply by 0.01).

5	500
10	1000
25	2500

Used in practice

Liquid viscosities are usually quoted in centipoise (cP); water is about 1 cP at room temperature.

One centipoise equals exactly one millipascal-second, the convenient bridge between the cgs and SI conventions.

Worked example. A dynamic viscosity of 0.01 P is 1 cP.

Frequently asked questions

How do you convert poise to centipoise?

Multiply the value in P by 100 to get cP. For example, 10 P = 1000 cP.

What is 1 P in cP?

1 P equals 100 cP.
