Estimate calories burned from your daily step count.
Distance = steps × average stride length. Calories ≈ distance(km) × 0.9 × (weight/70) as a rough walking-calorie estimate.

A step doesn't burn a fixed number of calories — it depends heavily on who's taking it. Research following 224 adults found body weight alone accounted for around 60% of the variance in calories burned while walking, with a strong correlation between weight and calorie burn per mile. As a rough anchor: a person around 70-75kg walking at a moderate pace burns approximately 0.04-0.06 calories per step, which works out to roughly 40 calories per 1,000 steps and about 400 calories per 10,000 steps — but a heavier person burns meaningfully more per step, and a lighter person burns less, for the exact same distance covered.
Pace, incline and terrain shift the number further: walking uphill, on sand, or at a brisk pace all raise the calorie cost per step compared to a leisurely stroll on flat pavement, sometimes substantially. The standard exercise-physiology formula behind most estimates is calories = time × MET × 3.5 × weight(kg) ÷ 200, where MET (metabolic equivalent) rises with intensity — a slow walk sits around 2.5-3 METs while a brisk walk can reach 4-5. Because of all these variables, treat any steps-to-calories figure, including this one, as a useful planning estimate rather than a precise measurement — a fitness tracker's heart-rate-based estimate will usually be closer to your true burn than steps alone.
For an average adult around 70-75kg walking at a moderate pace, roughly 400 calories — but this varies substantially with your own body weight, walking pace, and terrain. Heavier individuals burn more per step; a brisk pace or an incline both raise the total meaningfully above the flat, moderate-pace baseline.
Moving a heavier body the same distance takes more energy — a study of 224 adults found body weight explained around 60% of the variation in calories burned while walking, making it the single biggest factor in the calculation, ahead of step count or distance alone.
Yes, meaningfully more. Incline and soft or uneven terrain (sand, gravel, grass) increase the energy cost of each step compared to flat, firm pavement, because your muscles do additional work stabilising and pushing against the less efficient surface.
Not quite — a wearable that also factors in your heart rate typically produces a closer real-world estimate than steps alone, since heart rate responds directly to exercise intensity. A steps-based estimate is still a reasonable planning tool, but treat it as an approximation rather than a precise measurement.
