Menu units of measurement are the units of measurement specified for menu items (dish, goods or service).

Units of measurement are assigned to menu items and draft menu items in the Menu or Draft menu directories, respectively.

Units of measurement specified for a certain menu item are made available on the POS terminal after adding the menu item to an order.

The units of measurement used for menu items are managed in the Menu units of measurement directory.

Units of measurement must be categorised with a type, such as Volume, Quantity or Time. These types are defined by the user. They are used to categorise and sort units of measurement.

In some cases it appears to be convenient to measure quantities of the same menu item in different units of measurement. For example, sour cream can be measured in tablespoons or grams when it is used as an additive to soups, but it would be more preferable to measure it in glasses if it is an individual dish. In order to do this, one or more supplementary units of measurement can be added to the specification of menu item's units of measurement. You can specify any required supplementary units of measurement, and they do not need to be entered into the Menu units of measurement directory.

Supplementary units of measurement should be provided with a recalculation ratio to convert menu item's quantity expressed in primary units into quantities expressed in supplementary ones. Moreover, you should specify maximum and minimum values to indicate, when supplementary units of measurement will be used instead of primary ones.

If, when a menu item is added to an order, its volume falls between the minimum and maximum values of a supplementary unit defined for its specified unit of measurement, its volume will be displayed on the POS terminal in the supplementary unit of measurement.

Supplementary units of measurement are displayed only on the POS terminal screen. The basic units of measurement specified for menu items are always used in orders, bills and receipts.
