Walking burns roughly between 200 and 350 calories per hour at a moderate pace for an average person. The exact amount varies depending on body weight, walking speed, terrain, and walking intensity. For example, a person weighing around 155 pounds burns about 211 calories per hour walking at 2.5 mph, while faster speeds, uphill walking, or stair climbing can significantly increase calorie burn, potentially up to 500 calories per hour or more. Generally, most people burn about 30 to 40 calories per 1,000 steps, which translates to around 300 to 400 calories for 10,000 steps walked.
