Centistokes (cSt)
Centistokes (cSt) equals 10⁻⁶ m²/s. Water at 20°C has a kinematic viscosity of approximately 1 centistoke.
Centistokes is the standard industry unit for lubricants, fuels, and process fluids — from water (~1 cSt) to heavy oils.

1 cSt = 0.000001 m²/s
1 m²/s = 1000000 cSt
To convert centistokes to square meter per second, multiply by 0.000001.
To convert square meter per second to centistokes, multiply by 1000000.
Example: convert 10 cSt to m²/s
10 × 0.000001 = 0.00001 m²/s
Short background on the units used in this conversion.
Centistokes (cSt) equals 10⁻⁶ m²/s. Water at 20°C has a kinematic viscosity of approximately 1 centistoke.
Centistokes is the standard industry unit for lubricants, fuels, and process fluids — from water (~1 cSt) to heavy oils.
The square meter per second (m²/s) is the SI unit of kinematic viscosity — dynamic viscosity divided by density.
Square meters per second appear in fluid dynamics, CFD, and the definition of the stokes and centistokes units.
m²/s = cSt × 0.000001cSt = m²/s × 1,000,000, using the same exact factors as this converter.Jump to any viscosity-kinematic conversion starting from centistokes — including the reverse direction and every other unit in our dataset.
