The Exercise Calorie Calculator helps you estimate the total number of calories burned during physical activity based on your body weight, exercise duration, and the intensity of the workout. It uses the formula Calories = MET × Weight (kg) × Time (hours), where MET (Metabolic Equivalent of Task) values represent the energy cost of each exercise type. By knowing how many calories you burn during specific activities, you can plan workouts effectively, manage energy balance, and achieve fitness or weight management goals more accurately.
