Google has quite a few extra web search features that can make your browsing experience just a little more efficient. One of these is the Calculator feature. You can perform conversions and calculations on the fly right in your browser. Just input your calculation into the Google search field, press the “Enter” key, and a page with your result will be displayed.
For example, lets say you come across a page that states a distance between two destinations as being 357 miles, but you are more comfortable with kilometres. Just enter “357 miles in kilometres” (without quotes) into Google and you’ll instantly get the result “357 miles = 574.535808 kilometres”
You can also perform other conversions, such as pounds to kilograms, Celsius to Fahrenheit, modern numbers to Roman Numerals and many more. The calculator supports a raft of mathematical functions including addition, subtraction, division, multiplication, square root, logarithm and others.
Combine the Google Calculator with a tabbed browser that has built in Google Search such as Mozilla Firefox and you can quickly perform calculations without surfing away from the web page your are examining.
