square millimeter per second to square inch per second
Convert square millimeter per second (mm²/s) to square inch per second (in²/s). Use an editable kinematic viscosity converter, conversion formula, and reference table.
1 mm²/s = 0.0015500031 in²/s
Conversion formula
One square millimeter per second equals 0.0015500031 square inch per second. Multiply your value in square millimeter per second by this factor to get square inch per second. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 square millimeter per second:5 × 0.0015500031 = 0.0077500155 in²/s

About these measurements
Kinematic viscosity is dynamic viscosity divided by density.
The base reference used here is the square meter per second. One square millimeter per second is 0.000001 base units; one square inch per second is 0.00064516 base units.
Important distinctions
Compound units must match the quantity and dimension. Temperature intervals use size factors rather than temperature offsets. Calorie and BTU entries use the explicit definitions shown.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert mm²/s to in²/s?
Multiply the quantity in mm²/s by 0.0015500031. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the square inch per second to square millimeter per second converter.
