Guide: units and conversion

When adding quantities of referenced ingredients together for the ingredients list (i.e the ingredients properties of a Recipe), the parser tries its best to add apples to apples.

• If the quantities are defined in two different units of the same type and system, the largest unit is retained and the other quantity is converted. Example: 1%kg + 100%g will become 1.1%kg
• If the quantities are defined in units of the same type but in different systems (e.g. volume and mass), they will be first converted to the metric unit
• If the quantities are defined in incompatible units (e.g. text, or volume and mass), the quantities won't be added and a separate ingredient will be created in the list.

The following table of units and aliases is taken into account:
