About Square millimeter per second (mm²/s)
A metric kinematic-viscosity unit numerically equal to the centistoke (1 cSt = 1 mm²/s). Water at 20°C ≈ 1 mm²/s; SAE 30 motor oil ≈ 100 mm²/s at 40°C; heavy gear oil ~1,000 mm²/s. Mm²/s is the standard unit on lubricant datasheets (ISO VG grades use mm²/s at 40°C), hydraulic-fluid specs, and fuel-oil viscosity reports — the practical unit for day-to-day mechanical engineering.
About Stoke (St)
The CGS unit of kinematic viscosity equal to 1 cm²/s (= 100 cSt = 10⁻⁴ m²/s). Named after Irish mathematician George Stokes, whose work on viscous fluid flow (Stokes' law) underpins modern fluid mechanics. Stokes are occasionally used in geophysics for highly viscous fluids like lava and mantle rock, where values of 10³ to 10¹⁵ stokes are typical.
