How we calculate this These estimates use the ACSM Walking Metabolic Equation: VO₂ = 3.5 + (0.1 × S) + (1.8 × S × G) where S is speed in m/min and G is grade as a decimal. VO₂ is converted to calories using the standard 5.0 kcal per liter of oxygen consumed. This is the same equation used by exercise physiologists and certified personal trainers. Individual results vary based on fitness level, walking efficiency, and environmental conditions.
