May 11 is National Eat What You Want Day, and if what you want is donuts, Omni Calculator’s Do or Donut Calculator that tells you how many hours of cuddling you will need to burn off a donut.

Omni Calculator also has serious tools like conversions and camera speeds. But it’ll also let you know how many Wolfram|Alpha helium balloons you’ll need to fly.

What? You’ve never heard of Wolfram|Alpha? It’s the craziest info site I’ve ever seen. How many Scrabble points is the word “nerd,” or what’s your relationship to your uncle’s uncle’s son’s daughter’s cousin or ANYTHING ELSE that can be looked up, calculated, analyzed or configured??!! Wolfram|Alpha has the answers.
