About this steps to calories calculator
Stride length is about 41.4% of height, so 10,000 steps at 175 cm cover 7.25 km. At a normal 3 mph walk (3.5 METs) that takes about 1.5 hours and burns 3.5 × 70 kg × 1.5 h ≈ 368 kcal. A faster pace burns more per minute but the per-step cost changes less than people expect.
