`rho = "SG" * 1000 `

Enter a value for all fields

The **Mean Density of Solids and Liquids from the Specific Gravity** calculator uses the equation (ρ =SG • ρ_{w} ) 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 - (
**ρ**) The mean density of water (default is 1,000 kg/m_{w}^{3})

**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.

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).
