ResourceShelf reports this morning on a new Google feature.

Once again Google is catching-up. This time to AllTheWeb. Google announced today that you can use their search box as a basic calculator/converter. From the Google site, "To use Google's built-in calculator function, simply enter the expression you'd like evaluated in the search box and hit the Enter key or click the Google Search button. 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). You can also experiment with other numbering systems, including hexadecimal and binary." AllTheWeb announced their calculator/converter in April and May of this year. Btw, you can also use the Hotbot deskbar as a calculator and converter.

Today is the first time I'm seen either of these calculators. To me, it looks like Google's is FAR FAR superior. I can type in conversions like "100 miles to km" and it works in google, but not alltheweb. You can use units in your equations, and you can use advanced functions like sin(). Is there a convert function in alltheweb?
