persistenceUnit

persistenceUnit: string | undefined

Full name of a Unit (e.g. "Units.M") the magnitude is expressed in, for a property that has no persistence unit of its own — a coordinate, a plain double, or a JSON leaf.

Because this states what the value means rather than how it looks, the property's own persistence unit is authoritative when it has one: a persistenceUnit that names a different unit is ignored and a warning is logged.
