Enter the density of the air (kg/m^3) and the density of the water (kg/m^3) into the Air Specific Weight Calculator. The calculator will evaluate the Air Specific Weight. 

Air Specific Weight Formula

The following two example problems outline the steps and information needed to calculate the Air Specific Weight.

ASP = AD / WD

Variables:

  • ASP is the Air Specific Weight ( )
  • AD is the density of the air (kg/m^3) 
  • WD is the density of the water (kg/m^3) 

How to Calculate Air Specific Weight?

The following steps outline how to calculate the Air Specific Weight.


  1. First, determine the density of the air (kg/m^3). 
  2. Next, determine the density of the water (kg/m^3). 
  3. Next, gather the formula from above = ASP = AD / WD.
  4. Finally, calculate the Air Specific Weight.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

density of the air (kg/m^3) = 1000

density of the water (kg/m^3) = 998ASP = AD / WD = ?
