Unit definition
Centistokes (cSt) One centistokes equals 0.000001 square metre per second.
Unit history
Centistokes is represented here using its modern SI definition or an internationally accepted relationship to an SI base unit.
Step by step
1. Parse the value, including fractions.
2. Convert cSt to square metre per second.
3. Convert the base value to m²/s and apply your display precision.
Understand the result before using it
Centistokes to Square metres per second converts a value measured in Centistokes (cSt) into the equivalent value in Square metres per second (m²/s). The numerical value changes because the size and definition of the selected unit changes; the underlying quantity does not.
Calculated result
The conversion follows the displayed unit relationship. Display rounding can hide additional digits, and measured inputs cannot become more accurate merely by changing units.
Formula, assumptions, and example
Formula
result = input × 0.000001 ÷ 1
Assumptions
- Centistokes and Square metres per second represent the same kinematic viscosity quantity.
- The input is expressed in cSt; the output is expressed in m²/s.
- The unit definitions and conventional relationship shown on this page apply.
Worked example
1 cSt = 0.000001 m²/s. For another value, apply the same relationship and round only to the precision your source measurement supports.
When to use it
Good uses
- Read a cSt measurement in a document that expects m²/s.
- Compare a centistokes value with a value reported in square metres per second.
- Check the cSt to m²/s arithmetic before copying the result into another calculation.
Limitations
Common mistakes to avoid
- Dynamic and kinematic viscosity are different quantities and require density to convert between each other.
- Round the output to a precision justified by the original measurement.
- Verify safety-critical, regulated, laboratory, and contractual conversions against the controlling standard.

Questions about this calculation
How do I convert Centistokes to Square metres per second?
result = input × 0.000001 ÷ 1. Input is in cSt; result is in m²/s. 1 cSt = 0.000001 m²/s. The displayed digits may be rounded.
What is 1 cSt in m²/s?
1 cSt = 0.000001 m²/s. The displayed digits may be rounded.
Can I reverse the cSt to m²/s conversion?
Yes. Swap the source and target units in the converter. The reverse relationship converts m²/s back to cSt.
Is the Centistokes to Square metres per second result exact?
The conversion follows the displayed unit relationship. Display rounding can hide additional digits, and measured inputs cannot become more accurate merely by changing units.
