Steps To Calories Met

It first converts steps into distance and duration using your stride length and walking pace, then applies the MET formula for that intensity: MET × weight in kg × 0.0175 per minute. The result combines both your step data and body weight into an estimated calorie burn.

Faster walking has a higher MET value than slow walking, since it demands more energy per minute, so the same 10,000 steps burns more calories if walked briskly than if walked slowly. Step count alone doesn't capture intensity, which is why pace matters for an accurate estimate.

The 10,000 step figure originated from a 1960s Japanese marketing campaign rather than rigorous research, though later studies have found genuine health benefits from higher daily step counts, generally with diminishing returns above roughly 7,000-8,000 steps for many health outcomes. Treat it as a reasonable general target, not a precise scientific threshold.

Body weight, stride length, walking speed, and terrain (incline versus flat) all affect calorie burn independently of step count, so identical step totals can represent quite different amounts of actual work. Heavier individuals and faster walkers burn more calories for the same step count.

Both rely on similar underlying assumptions and formulas, so accuracy is comparable, generally within 10-20% of true energy expenditure for typical walking. Neither is a precise measurement; both are reasonable estimates useful for tracking relative trends over time.
