How do I calculate calories burned during exercise?
Use the Calories Burned Calculator. Enter your activity type, body weight, and exercise duration. The tool uses MET values to estimate energy expenditure in kilocalories. For example, a 70 kg person cycling at moderate pace for 30 minutes burns approximately 250 to 300 calories. Use our free sports calculators for accurate fitness estimates.

Results are accurate within 10 to 15 percent for most people under typical conditions. Intensity and fitness level affect actual burn.
VO2 max is the maximum amount of oxygen your body can use during intense exercise. It is a key indicator of cardiovascular fitness. A higher VO2 max means better endurance capacity. Athletes use it to set training zones. The calculator estimates it from your running pace or heart rate data for personalised training planning.
Calorie burn estimates are based on MET values and body weight. They are accurate within 10 to 15 percent for most people under typical conditions. Individual metabolism, fitness level, and effort intensity all affect actual burn. Use the results for planning and tracking trends over time rather than treating them as exact calorie targets.
