Walking 10,000 steps generally burns about 400 to 500 calories for an average person. This estimate corresponds to walking roughly 4.5 to 5 miles and taking about 1.5 to 2 hours at a casual pace of around 3.2 mph (5.15 kph)

. The actual calories burned can vary significantly based on several factors:

• Body weight: Heavier individuals burn more calories because moving a larger mass requires more energy

• Walking pace: A faster pace increases calorie burn. For example, walking 10,000 steps at 3 mph burns fewer calories than walking at 4 or 5 mph

• Terrain: Walking uphill or on an incline burns more calories than walking on flat ground

• Metabolism and fitness level: Individual metabolic rates and fitness can affect energy expenditure

To give an example, a person weighing about 187 lbs (85 kg) walking 10,000 steps at 3 mph burns approximately 469 calories, while walking at 2 mph burns around 559 calories due to longer duration

. Another estimate suggests a person weighing 150 lbs burns about 300-400 calories for 10,000 steps at a moderate pace

. In summary, 10,000 steps typically burn between 300 and 500 calories depending on individual characteristics and walking conditions, with 400-500 calories being a common average for many adults
