Unit definition
Square metres per second (m²/s) One square metres per second equals 1 square metre per second.
Unit history
Square metres per second 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 m²/s to square metre per second.
3. Convert the base value to St and apply your display precision.
Understand the result before using it
Square metres per second to Stokes converts a value measured in Square metres per second (m²/s) into the equivalent value in Stokes (St). 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 × 1 ÷ 0.0001
Assumptions
- Square metres per second and Stokes represent the same kinematic viscosity quantity.
- The input is expressed in m²/s; the output is expressed in St.
- The unit definitions and conventional relationship shown on this page apply.
Worked example
1 m²/s = 10,000 St. 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 m²/s measurement in a document that expects St.
- Compare a square metres per second value with a value reported in stokes.
- Check the m²/s-to-St 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 Square metres per second to Stokes?
result = input × 1 ÷ 0.0001 Using the displayed relationship, 1 m²/s equals 10,000 St.
How many Stokes are in one Square metres per second?
One Square metres per second is 10,000 Stokes. The displayed digits may be rounded.
Can I reverse the m²/s to St conversion?
Yes. Swap the source and target units in the converter. The reverse relationship converts St back to m²/s.
Is the Square metres per second to Stokes 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.
