Gas Density Calculator

How do you Calculate Gas Density?

Gas density can be calculated with a few different variables:

• Pressure


• Temperature


• Molecular mass

• GD = Gas Density


• P = Pressure


• MM = Molecular Mass


• R = Universal gas constant (8.314)


• T = Temperature

Understanding Your Results

When you hit calculate you will get your gas density result displayed in kilograms per cubic meter, by default. You can change this to another unit of measurement by choosing it from the dropdown menu.

How to Use the Gas Density Tool

Gas density calculators have never been this simple. You can use our tool to get a result in under a minute. The steps include:

1. Enter the amount of pressure.


2. Enter the temperature.


3. Enter the molecular mass.


4. Ensure your entries are correct and the units for each variable are correctly aligned with your intended values.


5. Hit calculate and get your results!

Example Calculation

Let's say you have a gas that has a molecular mass of 4 grams per mole, while it is 50 degrees Fahrenheit and there is 5,100 pascals of pressure at the moment. We can plug those values into each field of this tool to get our results.

With the values entered we can now hit calculate to get our answer of .0087 kilograms per cubic meter. We can convert that to another unit like pounds per cubic feet by selecting to from the dropdown menu and get our converted answer of .0005.
