Calorie Burn Calculator

Calculates energy expenditure using the ACSM metabolic equations for walking.

Manual Calculation Formula

VO2 (ml/kg/min) = (0.1 × speed in m/min) + (1.8 × speed × grade as decimal) + 3.5
Total Kcal = (VO2 × Weight in kg / 200) × Minutes

The ACSM Formula

This tool uses the American College of Sports Medicine (ACSM) metabolic equation for walking, valid for speeds between 1.9 and 3.7 mph. Speeds outside this range are better calculated using the running equation.
