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" or "Number". For example, the page for a "Has wattage" property might contain:

[[Corresponds to::1 W, Watt, Watts]]
[[Corresponds to::0.001 kW]]
[[Corresponds to::0.0013410220 hp, bhp, horsepower]]

For proportional conversions, as in the above example, datatype "Quantity" is set to the property. In case of non-proportional conversion datatype "Number" or an extra datatype is used. So far only datatype "Temperature" exists as an extra datatype of this kind.

Since Semantic MediaWiki 2.4.0 the position as suffix or prefix of the declared unit defines the display of the respective annotated data values.1

[[Corresponds to::€ 1]]
[[Corresponds to::1.06 USD, US$, $]]
