About this calculator
This calculator estimates the caloric expenditure of a physical activity using the MET (Metabolic Equivalent of Task) index. The calculation is simple: multiply the MET value of the activity by your weight in kilograms and by the time in hours. The result is an approximation of calories burned, useful for planning workouts or monitoring daily energy expenditure.
MET is a unit representing activity intensity. For example, walking at 5 km/h has a MET of 3.8, while running at 8 km/h has a MET of 8.3. The higher the MET, the more calories you burn per minute. The formula assumes that 1 MET equals 1 kcal/kg/h, i.e., the basal expenditure. Activities with MET above 1 indicate additional effort.
You can use this tool to compare different exercises, adjust workout duration according to your weight loss or fitness goals. Remember that the result is an estimate; individual factors such as metabolism, body composition, and movement efficiency can alter the actual value.
Precautions: the MET used is an average value and may not reflect your actual intensity. If you are new to exercise, consult a healthcare professional before starting any program. Use this calculator as a reference, not as an exact measure.
Frequently asked questions
What does MET mean?
MET stands for Metabolic Equivalent of Task. It is a measure of how many times more energy you expend during an activity compared to rest.
Does this calculator work for any activity?
Yes, as long as you know the MET value for the activity. You can find MET tables online for various activities.
Is the result accurate?
No, it is an estimate. Factors like age, sex, body composition, and fitness level affect actual expenditure.
Can I use it for weight loss planning?
Yes, as a reference. For weight loss, combine estimated caloric expenditure with a balanced diet.
Do I need special equipment?
No. You just need your weight, activity time, and the corresponding MET value.
