It would be great to be able to convert multiple units that are part of a single conceptual measurement, like the dimensions of a table top (area) or of a storage box (volume). For example, you could type "30 x 60 inches" and ask Soulver to convert this to "76.2 x 152.4 cm".

A common use case would be copying these dimensions from product descriptions, and having them converted to a desired target unit space.
