Viscosity measures a fluid's resistance to flow. Dynamic viscosity (Pa·s or cP) measures shear resistance. Kinematic viscosity (m²/s or cSt) = dynamic / density. Water at 20°C ≈ 1 cP.
- 1Dynamic: Pa·s (SI) or centipoise (1 cP = 1 mPa·s)
- 2Kinematic: m²/s (SI) or centistoke (1 cSt = 1 mm²/s)
- 31 Pa·s = 1,000 cP
- 4Kinematic viscosity = Dynamic / Density
Water at 20°C=Dynamic: ~1 mPa·s (1 cP); Kinematic: ~1 mm²/s (1 cSt)
| Fluid | Dynamic viscosity (mPa·s / cP) |
|---|---|
| Air (20°C) | 0.018 |
| Water (20°C) | 1.0 |
| Engine oil (SAE30) | ~100–300 |
| Honey | ~10,000 |
| Glycerol | ~1,400 |
