Centistokes to Stokes examples

1 cSt

1 cSt × 0.01 = 0.01 St.

10 cSt

10 cSt × 0.01 = 0.1 St.

100 cSt

100 cSt × 0.01 = 1 St.

Centistokes compared with Stokes

One St is 100 times as large as one cSt, so your number gets smaller when you convert centistokes to stokes and bigger when you convert back. If the answer is not smaller than what you typed, you multiplied instead of dividing.

About centistokes and stokes

Centistokes (cSt): The centistokes, exactly 1×10⁻⁶ m²/s. Stokes (St): The stokes, exactly 1×10⁻⁴ m²/s.

How to calculate Centistokes to Stokes step by step

  1. Enter the value in cSt (the starting unit).
  2. Multiply by 0.01, because 1 cSt = 0.01 St.
  3. The product is the value in St. To go back, divide by 0.01 or multiply by 100.
