Using Windows 7 Calculator to do Unit Conversions

While Google has a great Unit Conversion Tool Built in, that won’t help you on a plane, when you need to quickly figure out how many Feet per second 200 knots are before you crash in to the ocean will it?

If you start Calc.exe in Windows 7 and select Options –> Unit Calculator you will get a set of choices for the type of calculation to do, and the units to use.
