How Steps Translate to Calorie Burn
Calorie burn from walking depends on body weight, pace, and terrain. A rough estimate: 0.04–0.06 calories per step for a 70 kg (155 lb) person walking at a moderate pace. So 10,000 steps burns approximately 400–600 calories — or about 300–400 net calories above basal metabolic rate. Running steps burn more because the energy cost per step is higher even though you take fewer steps per kilometre.
More precise formula: Calories = MET × weight (kg) × duration (hours). Walking at 3.5 mph has MET ≈ 3.5; at 4.5 mph, MET ≈ 4.3. A 70 kg person walking 10,000 steps (≈ 80 minutes at 3.5 mph): 3.5 × 70 × 1.33 = 326 calories. Terrain and incline increase MET significantly — uphill walking at 5% grade raises MET to 5–6. Fitness trackers estimate calories using your weight, height, age, and heart rate for better accuracy.
Approximate Calories per 1000 Steps
| Body Weight | Walking (slow) | Walking (brisk) | Jogging |
|---|---|---|---|
| 55 kg (121 lb) | 31 cal | 35 cal | 55 cal |
| 70 kg (154 lb) | 40 cal | 45 cal | 70 cal |
| 85 kg (187 lb) | 48 cal | 55 cal | 85 cal |
| 100 kg (220 lb) | 57 cal | 65 cal | 100 cal |
