You've gotten great information but let me add that NONE of the number you'll get from commercial products are 100% accurate. That doesn't mean they're useless, it just means that everything is an estimate based on generalities and your specific numbers, esp calories burned, will vary all the time. For instance, when it calculates the number of miles, it uses the average stride length you enter but as pointed out, your actual stride length will vary according to what type of walking you're doing.
The calories burned are another estimate, based on your weight - heavier people burn more calories per mile because they are moving more weight. Most people use the general rule of 100 calories per mile but that's not necessarily 100% accurate for you on each and every walk you take. That's because even if you know exactly what rate your metabolism would burn, your personal calorie burn will vary all the time according to whether you are going uphill, downhill, even based on what type of surface [ie, walking in sand burns more calories per mile than walking on a sidewalk]. Making it more complex, your personal calorie burn will also vary according to what you ate, whether you are dehydrated, how much sleep you got, etc, because all of those things affect our metabolism. The only way to really know with 100% accuracy is to live in a laboratory with precise measuring eqpt all the time - obviously not very practical, haha!
So continue to use the pedometer as a guide and a motivation tool but don't get too caught up in whether you're getting exact numbers or not because it's not going to happen but the averages and estimates are 'good enough' to guide us to healthier living.
