About Calories burned calculator

The Calories Burned Calculator estimates how many calories you burn during physical activity using the MET (Metabolic Equivalent of Task) formula: calories = MET × body weight (kg) × duration (hours). MET values are standardised measures of energy expenditure — 1 MET equals resting metabolic rate, so running at 8 METs burns eight times the calories of sitting still. The calculator includes a dropdown of common activities with their established MET values: walking, jogging, running, cycling, swimming, weight training, yoga, and many more. Enter your weight (kg or lbs) and duration to get an instant estimate. Useful for workout logging, calorie budgeting, and understanding the energy cost of different activities.
