# Google Calculator

By Chris on August 13, 2003

Google now has a built-in calculator.

“The calculator can evaluate mathematical expressions involving basic arithmetic (5+2*2 or 2^20), more complicated math (sine(30 degrees) or e^(i pi)+1), units of measure and conversions (100 miles in kilometers or 160 pounds * 4000 feet in Calories), and physical constants (1 a.u./c or G*mass of earth/radius of earth^2.”

Enter this in the calculator: “answer to life the universe and everything”

With a little help, you can also have google find out in which year something happened: http://douweosinga.com/projects/googlehistory
