I already use google for converting metric to standard and such, but
why can't I do something similar to: 95 CND to USD for currency
conversion? It would be simple, yet useful, ie right up your alley.

I'd say it's a feature that going to be added to Google Finance once
they get all of the major bugs ironed out. It takes a lot of
up-to-the-minute financial reports to calculate conversion rates.
