Stride always derives from height × 0.415 (170 cm gives a 70.55 cm stride); the tool multiplies steps by stride for distance. Enter your height for a stride-calibrated figure — measured stride (walk 10 steps, divide distance) beats any estimate.
Steps × 0.04 kcal: 10,000 steps log 400 kcal regardless of pace. Estimates, not lab values; hilly routes burn more.
Yes when height is entered — stride derives from height automatically. Measured stride (walk 10 steps, divide distance) beats any estimate.
