A Density value represents a density in grams per cubic centimeter, pounds per cubic inch, etc. It is stored as a number of kilograms per cubic meter.

Note that since KilogramsPerCubicMeter is defined as Rate Kilograms CubicMeters (mass per unit volume), you can construct a Density value using Quantity.per:

density =
    mass |> Quantity.per volume

You can also do rate-related calculations with Density values to compute Mass or Volume:

mass =
    volume |> Quantity.at density


volume =
    mass |> Quantity.at_ density
