Centistokes to Square millimetres per second Converter cSt → mm²/s
1 centistokes (cSt) = 1 square millimetres per second (mm²/s). Type a value below — the conversion happens instantly, entirely on your device.
1 cSt = 1 mm²/s
1 centistokes = 1 square millimetres per second
1 × 1 = 1
1 cSt equals 1 mm²/s, so multiplying by 1 converts the value. The result describes the exact same quantity — only the measuring stick changes.
How to convert centistokes to square millimetres per second
square millimetres per second = centistokes × 1 — multiply the centistokes value by 1.
Example: 10 cSt = 10 mm²/s.
To convert the other way: centistokes = square millimetres per second ÷ 1

About the units
What is a centistokes?
One-hundredth of a stokes, equal to 1 mm²/s. The standard unit for lubricants — engine oils are typically rated by their centistokes at 40 °C and 100 °C.
What is a square millimetre / second?
One millionth of a m²/s (10⁻⁶ m²/s), numerically identical to the centistokes. The practical SI unit — water at 20 °C is about 1 mm²/s.
