How It Works
Calorie estimates use the MET (Metabolic Equivalent of Task) formula from the Compendium of Physical Activities:
calories = MET × weight (kg) × duration (hours)
MET values represent the energy cost of an activity relative to resting metabolism. A MET of 1.0 equals the energy burned at rest; running at 6 mph has a MET of ~9.8, meaning it burns 9.8× more energy than resting.
Limitations: This formula gives a population-average estimate and does not account for individual fitness level, age, gender, terrain, or heat/humidity. Actual calories burned may vary by ±15–30%.
