Exact cSt relation
Shows that 1 cSt equals 1 mm²/s.
Convert kinematic viscosity among SI, CGS, and common engineering units, including the exact equivalence between centistokes and square millimeters per second.
Converted value = input × source factor in m²/s ÷ target factor in m²/s. Key identity: 1 cSt = 1 mm²/s = 10⁻⁶ m²/s.
Shows that 1 cSt equals 1 mm²/s.
Includes SI, CGS, and imperial area-per-time units.
Explains the distinction from dynamic viscosity.
Kinematic viscosity describes momentum diffusion in a fluid and equals dynamic viscosity divided by density. Its SI unit is square meters per second (m²/s), but centistokes (cSt) and square millimeters per second (mm²/s) are widely used because typical liquid values are easier to read in those units.
The conversion uses m²/s as the internal reference. One centistoke is exactly one mm²/s, while one stoke equals 100 cSt. Imperial square-foot and square-inch units are also included for legacy specifications and engineering references.
Do not treat a kinematic value as a dynamic value merely because both are described as viscosity. Converting between them requires fluid density at the applicable temperature and pressure. As with dynamic viscosity, the physical value can vary with temperature and fluid composition.
| Input | What it means | Planning note |
|---|---|---|
| m²/s | SI kinematic viscosity unit | Typical liquid values can be very small. |
| mm²/s | One millionth of m²/s | Exactly equal numerically to cSt. |
| Centistoke (cSt) | One hundredth of a stoke | Common for oils and petroleum products. |
| Stoke (St) | CGS kinematic viscosity unit | 1 St equals 100 cSt. |

Prepare viscosity inputs for flow and Reynolds-number work.
It is dynamic viscosity divided by density and has dimensions of area per time.
Yes. One centistoke equals exactly one square millimeter per second.
One stoke equals 100 centistokes.
You need density. With compatible common units, cSt is approximately cP divided by density in g/cm³.
