Looking for a quick, easy and convenient way to calculate some of the fun facts and figures in your life?

Instead of simply guessing what your share should be and how much you want to leave for the wait staff, use a convenient tip calculator and eliminate the guesswork. Input the specifics of the items you ordered, the sales tax, and the tip percentage to get how much you owe.

• Creative Expression: The arts aren't that separate from the sciences after all. For example, you might want to calculate such numbers as the aspect ratio for a photograph so you can figure out how best to alter it to align with Facebook header image guidelines or to fit in your custom picture frame.
• Basic Conversions: What is 5/8 as a percentage instead? What is 22% of \$12,450? If you need to convert numbers from one form to another, a simple and straightforward percentage widget can deliver the right format quickly.
