Viscosity Converter

Background

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.

Industrial Applications

Viscosity is an important property in industrial applications such as lubrication, where the viscosity of a fluid can affect the performance and longevity of machinery. For example, in hydraulic systems, the viscosity of the fluid can determine the amount of pressure and flow rate, while in coolants, it can affect the heat transfer and corrosion protection.
