The SI unit of dynamic viscosity is the newton-second per square meter (N·s/m 2), also frequently expressed in the equivalent forms pascal-second (Pa·s), kilogram per meter per second (kg·m −1 ·s −1) and poiseuille (Pl). The CGS unit is the poise (P, or g·cm −1 ·s −1 = 0.1 Pa·s), [28] named after Jean Léonard Marie Poiseuille.

Ethylene - Dynamic and Kinematic Viscosity vs. Temperature and Pressure. Online calculator, figures and tables showing dynamic and kinematic viscosity of ethylene, C 2 H 4, also called ethene or acetene, at varying temperature and pressure - Imperial and SI Units.
18 sty 2024 · In this calculator, you will learn what the absolute viscosity of water is (commonly known as its dynamic viscosity) and how to convert it to kinematic viscosity. You will also learn how to calculate the viscosity of water and the effect of temperature on the viscosity of water using various methods.
The viscosity of water at 20 °C is 1.0020 millipascal seconds (which is conveniently close to one by coincidence alone). Most ordinary liquids have viscosities on the order of 1 to 1000 mPa s, while gases have viscosities on the order of 1 to 10 μPa s.
The SI unit of viscosity is \[N \cdot m/[(m/s)m^2] = (N/m^2)s \, or \, Pa \cdot s\), Table lists the coefficients of viscosity for various fluids. Viscosity varies from one fluid to another by several orders of magnitude.
Viscosity of liquids is expressed in a variety of units: with the standard SI unit being the Pascal second or Poiseuille. That unit does not prove to be convenient for many uses, but note that the viscosity of water at 20°C is almost exactly 1 if expressed in centipoise or milli-Pascal seconds.
