📌 Standard Benchmark Reference Values
Exact dimensional identity between centistokes and square millimeters per second.
Exact RatioAbout Centistokes (cSt)
One hundredth of a stokes (10⁻² St), equal to 10⁻⁶ m²/s (identically 1 mm²/s). Pure water has a kinematic viscosity of ≈ 1 cSt at 20 °C.
History: The universal commercial metric unit for engine oil, hydraulic fluid, and petroleum testing.
Common Uses: Kinematic viscosity viscometers (Cannon-Fenske, Ubbelohde tubes), automotive motor oils, aviation hydraulic fluid (Skydrol).
About Square Millimeter per Second (mm²/s)
A metric kinematic viscosity unit equal to 10⁻⁶ m²/s, identically equal to one centistokes (1 cSt). Water at 20 °C has a kinematic viscosity of ≈ 1.004 mm²/s.
History: Primary modern ISO metric kinematic viscosity grade unit (ISO 3448).
Common Uses: ISO VG industrial lubricant grading (e.g. ISO VG 32, 46, 68), automotive motor oil specifications.
❓ Frequently Asked Questions
How many Square Millimeters per Second are in 1 Centistokes?
There are exactly 1 Square Millimeters per Second in 1 Centistokes (1 cSt = 1 mm²/s).
What is the formula to convert Centistokes to Square Millimeter per Second?
The formula is: Square Millimeter per Second = Centistokes × 1. Since 1 Centistokes = 1 Square Millimeters per Second, multiply the value in Centistokes by 1.
How do I convert 1 cSt to mm²/s manually?
