**Kind**: `object`

## Fields

**`id`**: `ID!`

The ID of the measurement unit.

**`displayCode`**: `String!`

The short form shown next to quantities, for example 'kg'.

**`name`**: `String!`

The name in the default language.

---

**`predefinedCode`**: `String`

The code of a predefined measurement unit: the units Wawi ships with (UCUM codes such as 'kg' or '[lb_av]') and those created by the synchronisation with a shop. Empty for units created by users.
