Our calories burned calculator estimates the energy you expend during exercise and physical activities using MET (Metabolic Equivalent of Task) values. MET values represent the energy cost of an activity relative to sitting at rest. By multiplying your weight, the MET value, and the duration of the activity, we can estimate the calories burned. The calculator supports over 30 activities including running, cycling, swimming, walking, and gym exercises. Use it alongside our calorie calculator to understand your total daily energy balance.
