Pascal-second is the SI derived unit of dynamic viscosity, expressing a fluid's resistance to flow.
Derived from the SI units of pressure and time, the pascal-second became the standard scientific reference for dynamic viscosity in fluid mechanics.
Measurement system: International System of Units (SI, derived unit). SI equivalent: 1 Pa·s = 1 N·s/m².
