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 Square foot per second (ft²/s)

An imperial unit of kinematic viscosity used in US fluid-mechanics textbooks and petroleum engineering. 1 ft²/s ≈ 0.0929 m²/s = 92,903 cSt — a very large unit, appropriate for gaseous and highly mobile fluids but rarely for common liquids. Primarily encountered in US-edition fluid-mechanics literature and some legacy pipeline/petroleum engineering handbooks.
