1. What is Centistokes to Centipoise Conversion?

The conversion between centistokes (cSt) and centipoise (cP) is essential in fluid dynamics and rheology. Kinematic viscosity (cSt) can be converted to dynamic viscosity (cP) by multiplying by the fluid's specific gravity (SG).

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( cSt \) — Kinematic viscosity in centistokes
• \( SG \) — Specific gravity (dimensionless)
• \( cP \) — Dynamic viscosity in centipoise

Explanation: The formula accounts for the density of the fluid through the specific gravity factor, converting kinematic viscosity to absolute viscosity.

3. Importance of Viscosity Conversion

Details: This conversion is crucial in industries like petroleum, lubrication, and chemical processing where both viscosity measurements are used but different instruments may measure different types.

4. Using the Calculator

Tips: Enter kinematic viscosity in centistokes and the fluid's specific gravity. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between cSt and cP?
A: Centistokes (cSt) measures kinematic viscosity (viscosity/density) while centipoise (cP) measures dynamic viscosity (resistance to flow).

Q2: What is specific gravity?
A: Specific gravity is the ratio of a fluid's density to the density of water at 4°C (typically around 1.0 for water).

Q3: When is this conversion needed?
A: When you have kinematic viscosity data but need absolute viscosity for calculations, or when comparing measurements from different instruments.

Q4: What's the viscosity of water?
A: Water at 20°C has viscosity of about 1 cP and kinematic viscosity of about 1 cSt (SG ≈ 1).

Q5: Are there limitations to this conversion?
A: It assumes Newtonian fluid behavior and temperature-independent specific gravity. For non-Newtonian fluids, more complex models are needed.
