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.
