The Corresponds to property is a special property in Semantic MediaWiki with a built-in meaning: it gives the conversion factor for some unit of a physical quantity and the possible names for that unit. See the help page on custom units for details on using this special property.

You can use this special property with properties of datatype "Quantity"Holds values that describe quantities, containing both a number and a unit or datatype "Number"Holds integer and decimal numbers, with an optional exponent.

Proportional conversions[edit]

So far only datatype "Temperature"Holds temperature values (similar to type Quantity) exists as an extra datatype of this kind.
