The number of calories you burn walking depends on factors such as your weight, walking speed, distance, terrain, and walking duration.

• On average, a person weighing about 75 kg (165 lbs) burns around 200 to 500 calories per hour of walking, depending on pace and other factors

• Walking 10,000 steps typically burns about 300 to 500 calories for most people. For example, an average man (~75 kg) burns about 500 kcal for 10,000 steps, while a petite woman (~50 kg) burns around 290 kcal

• The speed of walking influences calories burned: walking at 3 mph burns roughly 469 kcal for 10,000 steps, at 2 mph about 559 kcal (but takes longer), and at 4 mph around 501 kcal for the same step count

• Another way to estimate is using METs (Metabolic Equivalent of Task). Walking at 3 mph is about 3.5 METs, meaning you burn 3.5 times the calories you would sitting. Calories burned = METs × weight (kg) × duration (hours). For example, a person weighing 80 kg walking 2 hours at 3 mph burns about 560 calories

• Roughly, people burn between 0.04 and 0.05 calories per step, so it takes about 2,000 to 3,000 steps to burn 100 calories, depending on weight and pace

To get a precise estimate for yourself, you can use online walking calorie calculators where you input your weight, walking speed, and duration or steps. In summary, the calories you burn walking vary widely by individual factors, but a rough estimate is about 300-500 calories per 10,000 steps or 200-500 calories per hour of moderate walking
