Unit definition
Square millimetres per second (mm²/s) One square millimetres per second equals 0.000001 square metre per second.
Unit history
Square millimetres 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 mm²/s to square metre per second.
3. Convert the base value to m²/s and apply your display precision.
Understand the result before using it
Square millimetres per second to Square metres per second converts a value measured in Square millimetres per second (mm²/s) 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
- Square millimetres per second and Square metres per second represent the same kinematic viscosity quantity.
- The input is expressed in mm²/s; the output is expressed in m²/s.
- The unit definitions and conventional relationship shown on this page apply.
Worked example
1 mm²/s = 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 mm²/s measurement in a document that expects m²/s.
- Compare a square millimetres per second value with a value reported in square metres per second.
- Check the mm²/s-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 Square millimetres per second to Square metres per second?
result = input × 0.000001 ÷ 1 Using the displayed relationship, 1 mm²/s equals 0.000001 m²/s.
How many Square metres per second are in one Square millimetres per second?
One Square millimetres per second is 0.000001 Square metres per second. The displayed digits may be rounded.
Can I reverse the mm²/s to m²/s conversion?
Yes. Swap the source and target units in the converter. The reverse relationship converts m²/s back to mm²/s.
Is the Square millimetres per second 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.
