The Swimming Calorie Calculator estimates the total number of calories burned during swimming based on your body weight, duration, and swimming intensity. It uses the MET (Metabolic Equivalent of Task) method with the formula Calories = MET × 3.5 × Weight × Time / 200, where MET varies depending on how intense the swim is. Light swimming burns fewer calories, while fast or competitive swimming burns significantly more. This calculator is ideal for swimmers and fitness enthusiasts to measure energy expenditure and manage training or weight loss goals effectively.
