Mean Density is the measure of the concentration of mass within a volume.  Substances can be characterized by their mean density.  Whether it's a metal, mineral, organic material, food, chemical or gas, the mean density has meaning. 

The formula for mean density is simply:

    ρ = m / v

where:

• ρ = mean density
• m = mass
• v = volume

Density Calculators

• Density from Mass and Volume: Computes density from mass and volume
• Mean Density Lookup:  Returns the mean density of hundreds of substances (metals, minerals, chemicals, fabricated materials, woods, foods, and more.
• Identify Possible Substances based on Density: Returns a list of substances within a density range.
