Apparatus, computer-readable medium, and method for calculating a mass of propellant in a propellant storage volume. A density of the propellant is calculated based on a detected pressure and temperature of the propellant and actual thermodynamic properties of the propellant. A volume of the propellant storage volume is calculated based on a measured nominal volume and changes to the nominal volume based on pressure. The mass of the propellant is calculated by multiplying the calculated volume of the propellant storage volume by the calculated density of the propellant in the propellant storage volume.
