The Kinematic Viscosity (ν) calculator computes kinematic viscosity (ν) based on the ratio of viscosity (μ) and the density of a fluid (ρ).
INSTRUCTIONS: Choose units and enter the following:
Kinematic Viscosity (ν): The calculator returns the kinematic viscosity in m²/sec.
Kinematic viscosity is also known as momentum diffusivity. Kinematic Viscosity (ν) is the ratio of dynamic viscosity (μ) and the density of a fluid (ρ). Since, μ is in units of (kg/m²)/ sec and ρ is kg/m³, the Kinematic Viscosity is expressed in units of m²/sec. The formula for kinematic velocity is:
υ = μ / ρ
