| Activity | Weight | Duration | MET | Estimated Calories |
|---|---|---|---|---|
| Walking, 3 mph | 70 kg | 30 min | 3.5 | 128.63 kcal |
| Running, 6 mph | 70 kg | 30 min | 9.8 | 360.15 kcal |
| Cycling, moderate | 80 kg | 45 min | 8.0 | 504.00 kcal |
| Swimming, moderate | 65 kg | 40 min | 5.8 | 263.90 kcal |
Formula Used
Calories burned = MET × 3.5 × body weight in kg ÷ 200 × minutes.
MET means metabolic equivalent of task. One MET is close to resting energy use. Higher MET values usually mean higher effort. This calculator also estimates net active calories by subtracting resting calories from gross calories.
Net active calories = gross calories - resting calories.
MET minutes = adjusted MET × exercise minutes.
How to Use This Calculator
Choose an exercise activity from the list. Enter body weight and select the correct unit. Add the workout duration. Adjust intensity if the workout was easier or harder than usual. Add weekly sessions for a training projection. Distance is optional. Use it when you need pace and calories per distance. Press the calculate button. The result appears above the form and below the header section.
Calories Burned During Exercise Guide
Why Exercise Calories Matter
Exercise calories help you understand workout demand. They also help you compare activities. A short intense run can burn more energy than a long easy walk. A heavier person usually burns more calories than a lighter person during the same activity. This happens because more mass requires more energy to move.
Understanding MET Values
MET values make exercise comparison easier. One MET represents resting effort. A five MET activity uses about five times resting energy. The calculator uses common MET estimates for walking, running, cycling, swimming, rowing, yoga, stair climbing, and strength training. You can also enter a custom MET when you know a better value.
Gross and Net Calories
Gross calories include total estimated energy during the exercise session. Net active calories remove the estimated resting portion. Both numbers are useful. Gross calories show total energy demand. Net calories show the extra burn caused by the activity itself. Many fitness reports use one method, so compare results carefully.
Using Intensity Correctly
Intensity changes the estimate. Easy effort may sit below the standard MET value. Hard effort may sit above it. Use the intensity factor as a practical adjustment. Keep it conservative for steady workouts. Use higher values only when the session was clearly demanding.
Planning Weekly Training
The weekly projection multiplies one session by your planned sessions. It is useful for exercise planning, weight management, and routine comparison. It is not a medical prediction. Food intake, recovery, sleep, hormones, and body composition also affect real progress. Use the result as a planning guide, not a guarantee.
Distance Based Review
Distance entries unlock pace and calories per distance. These values help runners, walkers, cyclists, and rowers compare workouts. A better pace with similar calories may show improved efficiency. A higher calorie rate may show harder effort. Track both trends over time for better insight.
FAQs
1. What is a MET value?
A MET value estimates exercise intensity. One MET is close to resting effort. Higher MET values mean the body uses more energy during the activity.
2. Are the calorie results exact?
No. The result is an estimate. Real calorie burn depends on fitness level, movement efficiency, body composition, terrain, temperature, and workout effort.
3. What is gross calorie burn?
Gross calorie burn is the total estimated energy used during exercise. It includes resting energy that your body would burn anyway.
4. What are net active calories?
Net active calories subtract resting calories from gross calories. This gives a clearer estimate of extra calories burned by exercise.
5. Which weight unit should I use?
Use the unit you know best. The calculator converts pounds to kilograms before applying the MET calorie formula.
6. Should I use the intensity factor?
Use it when effort differs from the standard activity estimate. Choose light, standard, hard, or very hard based on your session.
7. Why enter distance?
Distance is optional. It allows the calculator to estimate pace and calories per kilometer or mile for distance based workouts.
8. Can this help with weight loss planning?
Yes, it can support planning. Still, weight change also depends on nutrition, recovery, consistency, and health conditions.
