How many calories are burned by walking 1 mile?

The number of calories burned per mile of walking depends on the speed of the walk and the weight of the walker. The faster the walker is going and the more the walker weighs, the more calories she burns per hour.

According to the Mayo Clinic, a person who weighs 160 pounds and walks 2 miles per hour burns 204 calories per hour. That is equivalent to burning 102 calories by walking 1 mile. A person who weighs 240 pounds burns 469 calories per hour if she walks at 3.5 miles per hour. That means the person burns 134 calories per mile.
