About Square millimeter per second (mm²/s)
A metric kinematic-viscosity unit numerically equal to the CGS centistoke (1 cSt ≡ 1 mm²/s exactly = 10⁻⁶ m²/s). mm²/s is the universal working unit in lubricant engineering, fuels, and hydraulic-fluid specification because typical values fall in the convenient 1-1,000 range. Reference values: water at 20 °C 1.00 mm²/s (the famous calibration baseline), SAE 30 engine oil at 40 °C ~100 mm²/s, heavy gear oil 1,000-2,000 mm²/s, EP-90 gear oil 220-330 mm²/s, ATF (automatic-transmission fluid) ~38 mm²/s at 40 °C. Industry standards: ISO 3104 (Petroleum products — kinematic-viscosity test method), ASTM D445 (the standard US capillary-viscometer test), ISO VG (Viscosity Grade) lubricant classification system — VG 32, VG 46, VG 68, VG 100, VG 220 numbers ARE the cSt/mm²/s value at 40 °C, ±10%. Marine residual fuel oil (HFO) per ISO 8217 quotes viscosity in mm²/s at 50 °C (RMK 700 grade = 700 mm²/s at 50 °C).
About Square meter per second (m²/s)
The SI unit of kinematic viscosity (ISO 80000-4 §4-33) — dynamic viscosity divided by density (ν = μ/ρ), with dimensions of length squared per time. Kinematic viscosity captures how readily a fluid flows under inertial forces relative to viscous resistance, and appears directly in the dimensionless Reynolds number (Re = ρVL/μ = VL/ν) that determines laminar vs turbulent flow regimes. m²/s is the reference unit in fluid-mechanics research, CFD solver inputs (Ansys Fluent, OpenFOAM, COMSOL, ANSYS CFX), and Reynolds-number calculations. Real-world liquid values typically span 10⁻⁶ to 10⁻³ m²/s, so most practical engineering uses mm²/s (= 10⁻⁶ m²/s = 1 cSt). Reference values: air at 20 °C 1.5 × 10⁻⁵ m²/s, water at 20 °C 1.004 × 10⁻⁶ m²/s, SAE 10W-30 motor oil ~70 × 10⁻⁶ m²/s at 100 °C, glycerin 1.18 × 10⁻³ m²/s — six orders of magnitude variation across common fluids.
