Fillet uses 3 types of measurement units: mass units, volume units, and Abstract units
Mass units and volume units are standard units of measurement.
Abstract units are custom units of measurement.
You can create new Abstract Units and they will be saved for future use.
To use Abstract Units in calculations, you must specify conversion.
This means you must specify the conversion between the Abstract Unit and a standard measurement unit:
- Abstract unit to mass unit,
- Abstract unit to volume unit,
You can also specify conversion for an Abstract unit to mass unit and volume unit.
