  • Dynamic Viscosity an overview ScienceDirect Topics

    Dynamic viscosity: The SI physical unit of dynamic viscosity (μ) is the Pascal-second (Pa s), which is identical to 1 kg m −1 s −1. The physical unit for dynamic viscosity in the centimeter gram second system of units (cgs) is the poise (P), named after Jean Poiseuille. It is more commonly expressed, particularly in ASTM standards, as centipoise (cP).
