How It Works

Three conversions do all the work: your height gives a stride length, steps × stride gives distance, and distance × body weight gives a rough energy cost. All math is internal metric.

Stride From Height

Walking studies have long found stride length close to a fixed fraction of height — the classic regression constants are about 0.413 × height for men and 0.419 × height for women (in the same units; 170 cm × 0.413 ≈ 70 cm). These are average-population regression constants, not measurements of you: your real stride differs with leg length, pace and terrain, which is exactly why a GPS walk on flat ground is a better distance log than any step formula.

The Half-a-Calorie-per-Kilo-per-Km Rule

Net walking cost is commonly approximated as ~0.5 kcal per kg of body weight per km — so 70 kg over 5 km is roughly 70 × 5 × 0.5 = 175 kcal. It lines up with the Compendium of Physical Activities, where level walking at a moderate 4–5 km/h sits around 3.5–4 METs with a substantial seated-metabolism component removed. That makes it a gentle approximation: the "brisk" option nudges it +15% for the faster cadence (~100+ steps/min), but wind, surface and fitness all move the real number too.

Why Walking Pace Varies

Leisurely strolling (~3 km/h) and brisk walking (~5–6 km/h) share the same steps but differ in stride and cadence, so the same 10,000 steps can be 7 km or 8.5 km of distance — and the harder effort per minute. Pick the intensity that matches your usual walk; if it changes through the day, the leisurely figure is the safer, more conservative choice.
