I
noticed a while ago that google toolbar in
both firefox and
IE has a very nice
feature. As you type a search, it will do an autocomplete based on
popular searches. However, if you put in google calculator
terms, it will also provide
the calculator answer in the dropdown, so you don’t even have to hit
enter to see the answer. I used this yesterday, for instance, to
determine how many teaspoons it takes to make 1/2 a tablespoon (1/2
tblsp in tsp).
