How to calculate calories burned walking

I'm new here, but i figured out that under the exercise tab, there's a data log section that i type in "walking" and it gives you options for brisk, etc.
Hit "add exercise" AND search walking in the data above it! just click on which walk you want and put how many minutes. the computer does the REST! wooohooo!!!
hope that helps!!!! I google everything, too!!! haha

I heard from a doctor that a mile is 100 calories pretty much however you do it (walking, jogging, running, whatever)

thx for the website info
