Google

I was looking for a website to convert kg to lb. When I entered convert 80 kg to lb I faced the answer on the top! Then I realized that Google has some interesting features.

Google is a calculator.
Example: wanna know what is 568 times 47? just google for 568*47!

Converts measures and weights:
Example: I want to know how many pounds is 106 kg. I google for convert 106 kg to lb

wanna find the definition of a word? just add the word "define" before the word you are looking for
Example: affirmative action

looking for an address? just google it!
Example: 10 Fifth Ave New York NY

There are some other features for google. Just have a look at this.
