1. What is Poise to Centipoise Conversion?

The poise (P) and centipoise (cP) are units of dynamic viscosity. The conversion between them is straightforward as 1 poise equals 100 centipoise. This conversion is commonly used in fluid mechanics and engineering applications.

2. How Does the Calculator Work?

The calculator uses the simple conversion formula:

Where:

• \( cP \) — Viscosity in centipoise
• \( P \) — Viscosity in poise

Explanation: The conversion factor of 100 comes from the definition of centipoise as 1/100 of a poise.

3. Importance of Viscosity Conversion

Details: While poise is the standard unit in the CGS system, centipoise is more commonly used in practical applications because it provides more convenient numbers (water at 20°C has a viscosity of about 1 cP).

4. Using the Calculator

Tips: Simply enter the viscosity value in poise (P) and the calculator will automatically convert it to centipoise (cP). The input must be a positive number.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between poise and centipoise?
A: Centipoise is simply 1/100 of a poise. 1 P = 100 cP, just like 1 meter = 100 centimeters.

Q2: What are typical viscosity values in cP?
A: Water at 20°C is about 1 cP, while honey is about 10,000 cP, and molasses can be 100,000 cP.

Q3: Why is centipoise more commonly used than poise?
A: Centipoise provides more convenient numbers for most common fluids, similar to why centimeters are often more practical than meters for small measurements.

Q4: Is this calculator valid for all types of fluids?
A: Yes, the conversion factor is the same regardless of the fluid type, as it's simply a unit conversion.

Q5: What's the SI unit equivalent for poise?
A: The SI unit for dynamic viscosity is Pascal-second (Pa·s), where 1 Pa·s = 10 P = 1000 cP.
