Use
In this IMG activity you specify which units of the dimension mass correspond to which units of the dimension volume. The system then uses these units to convert from mass to volume and vice versa, for example, in the Quantities and Input and Output formula views. By making appropriate selections, you can ensure that the number values for mass and volume are of a similar scale.
Example
Ethanol has a density of 0.79.
If you pair the unit of mass kg with the unit of volume liters, the system calculates a volume of 5.06 l from the mass of 4.00 kg. The number values have the same order of magnitude and are easy to reconcile.
If you pair the unit of mass kg with the unit of volume m3, the system calculates a volume of 0.00506 m3 from the mass of 4.00 kg. The number values have different orders of magnitude and are harder to reconcile.
