The Mean Density of Solids and Liquids from the Specific Gravity calculator uses the equation (ρ =SG • ρw ) to compute the mean density of a substance based on the mass density to density of water under standard conditions (4ºC) and the Specific Gravity (SG).
 
INSTRUCTIONS: Choose units and enter the following:

  • (SG) The specific gravity
  • (ρw) The mean density of water  (default is 1,000 kg/m3)

Mean Density (ρ): The calculator returns the mean density (ρ) in kilograms per cubic meter.  However this can be automatically converted to other density units via the pull-down menu.

Mean Density

The mean density of water in this equation has a default of 1000 kg/m³.  However, the user can enter other values for the denominator density.  For gases, the specific gravity is nearly always based on the mean density of air at room temperature (21ºC).
