# Ethylene - Dynamic and Kinematic Viscosity vs. Temperature and Pressure

The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress .

For further definitions, go to Absolute (dynamic) and kinematic viscosity . Absolute or dynamic viscosity is used to calculate Reynold's Number to determine if a fluid flow is laminar, transient or turbulent.

Tabulated values of ethylene viscosity and viscosity units conversion are given below the figures.

### Online Ethylene Viscosity Calculator

The calculator below can be used to calculate ethylene dynamic or kinematic viscosity at given temperatures and atmospheric pressure.
The atmospheric boiling point of ethylene is -104 °C (-155 °F), which gives a shift in viscosity at that temperature.

The output dynamic viscosity is given as Pa*s, N*s/m2, cP, mPa*s, lbf *s/ft2and lbm /(ft*h),
while the kinematic viscosity is given as cSt, m2/s, and ft2/s

Choose the actual unit of temperature:
