Performing unit conversions in Spotlight Is there a way to perform unit conversions from within Spotlight?  For example I want to convert 1 ft^3 to cm^3 in spotlight.
There isn't really any way to customize the Spotlight menu or add features to it.

I know it would be nicer to display the results inline, but it doesn't take that long to search with Google either:



There are some Alfred extensions that use Google's calculator API or Wolfram Alpha's API, but they display the results as notifications, so you can't copy them as text.
