Kinematic Viscosity Converter
Kinematic viscosity is dynamic viscosity divided by density — the property that governs how a fluid flows under gravity. The SI unit is the square meter per second, but lubricant and fuel specifications almost always use centistokes, which equal square millimeters per second.
25 units supported Base unit square meter per second (m²/s)
Centistokes and Square Millimeters per Second are the same size, so the value does not change. How this is calculated
About kinematic viscosity conversion
Kinematic Viscosity conversion is commonly needed when engine oil grades, hydraulic fluid selection, and fuel specifications. Centistokes and square millimetres per second are the same size, so an oil quoted in either figure needs no conversion at all.
