Viscosity (Kinematic) Converter
Kinematic viscosity is dynamic viscosity divided by the fluid’s density. The SI unit is the square metre per second (m²/s); the centistoke (cSt), equal to 1 mm²/s, is the standard unit for oils.
1 Square Meter/Second = 1,000,000 Centistokes
How to convert Square Meter/Second to Centistokes
One Square Meter/Second equals 1,000,000 Centistokes, so multiply any value in m²/s by 1,000,000 to get cSt. To convert back, divide by 1,000,000 — or multiply by 0.000001.
cSt = m²/s × 1,000,000
Example: 25 m²/s × 1,000,000 = 25,000,000 cSt.
