I discovered a cool use for Wolfram-Alpha the other day, in particular, calculating calories used on a bike ride.

Okay, I know it’s not 100% accurate, especially since it can’t look at such things as gear ratio, terrain, tire drag, etc.  However, it’ll still get you in the neighborhood of your calorie usage if you do your best to input as much accurate information as possible.

You can also change the activity type from bicycling, to running, walking, etc.
