Enter the dynamic viscosity (Pa-s) and the kinematic viscosity  (m^2/s) into the Density From Viscosity Calculator. The calculator will evaluate and display the Density From Viscosity.

## Density From Viscosity Formula

The following formula is used to calculate the Density From Viscosity.

p = u / k
• Where p is the Density From Viscosity (kg/m^3)
• u is the dynamic viscosity (Pa-s)
• k is the kinematic viscosity  (m^2/s)

To calculate the density from viscosity, divide the dynamic viscosity by the kinematic viscosity.

## How to Calculate Density From Viscosity?

The following example problems outline how to calculate Density From Viscosity.

Example Problem #1:

1. First, determine the dynamic viscosity (Pa-s).
1. The dynamic viscosity (Pa-s) is given as: 500.
2. Next, determine the kinematic viscosity  (m^2/s).
1. The kinematic viscosity  (m^2/s) is provided as: 250.
3. Finally, calculate the Density From Viscosity using the equation above:

p = u / k

The values given above are inserted into the equation below:

p = 500 / 250  = 2 (kg/m^3)

Example Problem #2:

For this problem, the variables needed are provided below:

dynamic viscosity (Pa-s) = 250

kinematic viscosity  (m^2/s) = 965

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer. p = u / k  = ?
