Convert Stokes to Poise

Type the number of stokes that you wish to convert to poise.

1 St (stokes) = 0.001 P (poise)

How to Convert Stokes to Poise

The stokes and poise are both units of viscosity. By definition, 1 poise equals exactly 1000 stokes. This means to convert stokes to poise, you divide by 1000.

Formula

poise = stokes ÷ 1000

Step-by-Step Example

Convert 5 St to poise:

1
Convert 5 St to poise

We need to convert stokes to poise

2
Apply the formula

Since 1 P = 1000 St, divide by 1000

5 ÷ 1000 = 0.005

Answer

5 St = 0.005 P

About These Units

Stokes (St)

The stokes (St) is the CGS unit of kinematic viscosity equal to 1 cm²/s or 100 centistokes. Named after physicist George Stokes. Water at 20°C: 0.01 St, light motor oil: 0.3-1 St at 40°C. One stokes = 10⁻⁴ m²/s. Common in technical literature.

Poise (P)

The poise (P) is the CGS unit of dynamic viscosity equal to 0.1 Pa·s or 100 centipoise. Named after Jean Léonard Marie Poiseuille who studied blood flow. Water is 0.01 P, glycerin is ~15 P at 20°C. One poise = 1 g/(cm·s) = 1 dyn·s/cm².
