How calories burned are estimated
Every activity has a MET value (Metabolic Equivalent of Task), a number that says how hard the activity works your body compared with resting. The calculation is simple:calories = MET × body weight in kilograms × time in hours. If you entered pounds, the tool converts them to kilograms first (1 lb is about 0.4536 kg). Because weight and time are both in the formula, heavier people and longer or harder sessions burn more calories, exactly as you would expect.
For example, brisk walking is roughly 3.5 METs while running is close to 9.8 METs, so for the same body weight and the same number of minutes, running burns nearly three times as many calories as walking. The per-minute and per-hour figures show your burn rate, which is handy for comparing activities at a glance.
An estimate, not medical advice
These numbers are a general estimate, not a precise measurement. MET tables use population averages, so your real calorie burn will vary with your age, sex, fitness, body composition, intensity and metabolism. Use the result as a rough guide for planning workouts or comparing activities, not as an exact calorie count.
Health note: This calculator is for general information only and is not medical or dietary advice. Calorie estimates alone cannot guide weight loss, training or nutrition decisions. Always consult a qualified doctor, dietitian or fitness professional before making changes to your diet or exercise.
Frequently asked questions
How are calories burned calculated?
The tool uses MET values: calories = MET × your body weight in kilograms × time in hours. A higher MET activity, more body weight or a longer session all raise the total.
What is a MET value?
A MET compares an activity's energy use with resting. Sitting still is about 1 MET, brisk walking around 3.5 METs and running close to 10 METs.
Why does body weight change the result?
Heavier bodies use more energy to move, so a heavier person burns more calories doing the same activity for the same time.
How accurate is the estimate?
It is a rough guide. Your real burn depends on age, fitness, intensity and metabolism, which average MET tables cannot capture exactly.
Is my data uploaded?
No, everything is calculated on your device and nothing is sent anywhere.
