How It Works

How to Convert Poise to Pascal-Seconds

Formula

Pa·s = Poise x 0.1

The Poise (P) is the CGS unit of dynamic viscosity, while the Pascal-second (Pa·s) is the SI unit. One Poise equals 0.1 Pa·s because 1 P = 1 g/(cm·s) and converting grams to kilograms and centimeters to meters introduces a factor of 0.1.

Common Viscosities

| Fluid | Approximate Viscosity | |---|---| | Water at 20°C | 0.01 P (1 cP) | | Olive oil | 0.8 P (80 cP) | | Honey | 20-100 P (2,000-10,000 cP) |

Worked Example

Convert 10 Poise to Pascal-seconds.

poise = 10
  1. 01Apply the conversion: 1 P = 0.1 Pa·s
  2. 02Pa·s = 10 * 0.1 = 1.0 Pa·s
  3. 03Also: 10 P = 1,000 cP (centipoise)
