Conversion examples (rounded)

  • 1 mm²/s = 0.000001 m²/s
  • 10 mm²/s = 0.00001 m²/s

Some supported units: m²/s · mm²/s · cSt · St · ft²/s (5 units in this category).

1 cSt equals 1 mm²/s; density is required to convert to dynamic viscosity.

The nearby list shows the reference unit and up to two rows on either side. Expand it to see every unit. Check SI / metric, imperial / US customary and other definitions before important use.

How do you convert cSt to mm²/s?

1 cSt equals 1 mm²/s, or 0.000001 m²/s.

  • 1 cSt = 1 mm²/s
  • 1 cSt = 0.000001 m²/s
What matters when comparing oil viscosity?

Use values measured at the same temperature and conditions. Unit conversion does not correct temperature differences. Conversion to dynamic viscosity in Pa·s also requires density.
