Quick Answer — How Many Miles and Calories Is X Steps?
The core formula: Distance (mi) = Steps × Stride length (ft) ÷ 5,280, where stride length is estimated as Height (in) × 0.413 for women or × 0.415 for men.
Calories: Calories = MET × Weight (kg) × Duration (hours), where duration comes from dividing your distance by your walking or jogging speed, and MET is the metabolic equivalent for that pace (2.8 for a leisurely walk, 4.3 for a brisk walk, 8.3 for jogging).
Quick reference (brisk walk, 3.5 mph):
- 5,000 steps, 5'6" female, 150 lb → 2.15 mi = 3.46 km, ~52 min, ~180 kcal
- 10,000 steps, 5'6" female, 150 lb → 4.30 mi = 6.92 km, ~74 min, ~360 kcal
- 10,000 steps, 5'10" male, 180 lb → 4.58 mi = 7.38 km, ~79 min, ~460 kcal
Worked example: 10,000 steps for a 5'6" (66 in) woman weighing 150 lb, walked at a brisk 3.5 mph pace: stride = 66 × 0.413 = 27.26 in (2.27 ft). Distance = 10,000 × 2.27 ÷ 5,280 = 4.30 miles. That takes about 74 minutes at 3.5 mph and burns roughly 360 kcal.
The reason 'steps × a flat number' calorie estimates are unreliable is that they ignore body weight and pace, both of which change calorie burn by a large factor for the identical step count.
