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.

Exact conversion factors in both directions, plus a worked example.
1 cSt = 0.01 St
1 St = 100 cSt
To convert centistokes to stokes, multiply by 0.01.
To convert stokes to centistokes, multiply by 100.
Example: convert 10 cSt to St
10 × 0.01 = 0.1 St
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.
Stokes (St) equals 10⁻⁴ m²/s — the CGS unit of kinematic viscosity. One stokes equals 100 centistokes.
Stokes appears in rheology literature and older engineering references alongside the centistokes subunit.
St = cSt × 0.01cSt = St × 100, 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.
