Viscosity = resistance to flow. Dynamic: Pa·s (SI) or cP (industry). Kinematic: m²/s or cSt. Essential for lubrication and chemical engineering.
Dynamic vs Kinematic
Dynamic (Pa·s, cP) = internal resistance. Kinematic (m²/s, cSt) = dynamic ÷ density. Engine oil: 100–200 cP at room temp.
Common Viscosities
Water: ~1 cP. Honey: 2,000–10,000 cP. Motor oil: 50–1,000 cP depending on grade/temperature.

Process Engineering
Polymer melts: 100–100,000 Pa·s. Convert for international equipment specs.
Food Industry
Tomato sauce: ~50,000 cP. Convert for international food processing standards.
Frequently Asked Questions
How do you convert cP to Pa·s?
Divide by 1,000. 100 cP = 0.1 Pa·s. 1 cP = 0.001 Pa·s = 1 mPa·s.
Viscosity of water?
At 20°C: ~1.002 cP (dynamic) or ~1.004 cSt (kinematic).
cP vs cSt?
cP = dynamic viscosity. cSt = kinematic viscosity. cSt = cP ÷ density (g/cm³).
