WebWorkerDaily has the whole list. Here are a few from the list:
- Use Google as a spelling aid. Entering a word into Google is a quick way to see if you have the right spelling. If it’s incorrect, Google will suggest the correct spelling instead.
- Use Google as a calculator. Google has a built-in calculator — try entering a calculation like 110 * (654/8 + 3).
- Find out what time it is anywhere in the world. Just search for “time” and then the name of the city. For example, try: time St. Louis
- Area code lookup. Need to know where a phone number is located? Google will let you know where it is, and show you a map of the area, too. For example: 314
- Exclude specific terms with the – operator. You can narrow your searches using this operator. For example, if you’re looking for information about American Idol but don’t want anything about Simon Cowell, you could try: “american idol” -cowell
