Viscosity is a measure of a fluid’s resistance to flow. In the International System of Units (SI) the dynamic viscosity is expressed in Pascalβseconds (PaΒ·s), while the CGS system uses centipoise (cP), where 1β―cP = 0.001β―PaΒ·s. Converting between these units is essential for engineers who work across different standards.
The Saybolt Universal Seconds (SSU) is a historical kinematic viscosity measurement used primarily in the petroleum industry. Although SSU is technically a measure of kinematic viscosity, it is often related to dynamic viscosity through empirical correlations. One common approximation is:
By chaining these relationships, you can convert from any of the three representationsβcP, PaΒ·s, or SSUβto the others, enabling seamless data exchange between legacy specifications and modern engineering calculations.
