Pressure

A Pressure value represents a pressure in kilopascals, pounds per square inch, atmospheres etc. It is stored as a number of pascals.

Note that since Pascals is defined as Rate Newtons SquareMeters (force per unit area), you can construct a Pressure value using Quantity.per:

pressure =
    force |> Quantity.per area

You can also do rate-related calculations with Pressure values to compute Force or Area:

force =
    area |> Quantity.at pressure


area =
    force |> Quantity.at_ pressure
