GoogleCalculator

GoogleSearch can also be used as a calculator that can interpret some fairly free-form expressions. For example, search for:

• 2 + 2
• two plus nine
• square root of eighty-one
• 3^27
• 30 metres in inches
• eight thousand square millimeters divided by 4 in hectares

Which is pretty handy; it's better than most physical calculators out there. - EssKay
