The answer depends on your weight, what you walk on (sand, grass, hard pavement ), whether you are walk on flat ground, a slight incline, or a hill, as well as how far you walk and the pace of your walk.
For example, a person weighing 150 pounds will burn about 3 or 4 calories a minute walking at 3 miles an hour. The same person walking up a 15 degree slant can burn 4 times that amount. Plus, things like walking in sand or grass is more difficult and that would burn more calories. In addition, a person weighing 300 pounds will burn more calories because they have more weight to carry.
You can't tell unless you have a specific device to tell you. However, you do not need to worry about the math because when walking for weight loss is done correctly (there is a correct cardio way to do it) it is
excellent fat burning exercise.
