About Centistoke (cSt)
A CGS kinematic-viscosity unit equal to exactly 0.01 stoke = 1 mm²/s = 10⁻⁶ m²/s. Centistokes is the traditional and still-dominant working unit in the global lubricant industry, petroleum products, and fuel-oil specifications. Industry standards using cSt directly: ISO 3104 / ASTM D445 (the universal capillary-tube kinematic-viscosity test method — every lubricant data sheet in the world traces back to this test), ISO 8217 (marine fuels — DM and RM grades all spec viscosity in cSt at either 40 °C or 50 °C; e.g., MGO 'Marine Gas Oil' is ≤ 6.0 cSt at 40 °C; HFO 'Heavy Fuel Oil' is up to 700 cSt at 50 °C), ASTM D2270 (Viscosity Index calculation from kinematic viscosity at 40 / 100 °C), SAE J300 (engine-oil grading at 100 °C and CCS-tested low-temp cP), ISO VG industrial-lubricant grading (the VG number = cSt at 40 °C, ±10%).
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).
