Calories Burned Calculator
Free Calories Burned Calculator using MET values. Calculate calories burned during running, walking, cycling, swimming, HIIT, yoga, and 18+ activities. Track exercise calories with comparison charts.
About This Calculator
The Calories Burned Calculator helps you estimate energy expenditure during any physical activity using MET (Metabolic Equivalent of Task) values from the 2011 Compendium of Physical Activities. Whether you are running, walking, cycling, swimming, or doing HIIT, yoga, or weightlifting, this tool provides personalized calorie burn estimates based on your body weight and exercise duration.
The calculation uses the standard MET formula: Calories = MET value × weight (kg) × duration (hours). MET values represent the ratio of working metabolic rate to resting metabolic rate, where 1 MET equals resting energy expenditure. For instance, running has a MET of 9.8 (nearly 10 times resting), while walking has a MET of 3.5. The formula is a simplified version of the more precise equation that accounts for oxygen consumption (VO₂), but the simplified approach provides accurate estimates within 5% for most activities.
Our calculator supports 18+ activities including running, walking, cycling, swimming, HIIT, yoga, weightlifting, dancing, basketball, tennis, soccer, hiking, elliptical, stair climbing, rowing, pilates, kickboxing, and jump rope. You can also manually adjust the MET value if your activity intensity differs from the standard. The results include total calories burned, calories per hour, and a comparison chart that visualizes your activity against others.
Regional Notes
India (IN): The calculator uses metric units (kg) by default. Popular activities include walking, jogging, yoga, and cycling. The results can help track energy expenditure for weight management and fitness goals.
United States (US): While the calculator uses kg for weight, the MET formula is universal. Common activities include running, walking, cycling, and gym workouts. Use the results alongside dietary tracking for effective weight management.
United Kingdom (UK): The calculator follows the standard MET-based approach used by the NHS and sports science professionals. Use it to estimate calorie burn for activities like brisk walking, cycling, and swimming as part of your fitness routine.
Frequently Asked Questions
How are calories burned calculated?
Calories burned are calculated using the MET (Metabolic Equivalent of Task) formula: Calories = MET value x weight (kg) x duration (hours). MET measures the energy cost of physical activities. For example, running has a MET of 9.8, while walking has a MET of 3.5. A 70 kg person running for 30 minutes burns approximately 343 calories.
What is a MET value?
MET stands for Metabolic Equivalent of Task. It represents the ratio of working metabolic rate to resting metabolic rate. 1 MET equals resting energy expenditure. Running has 9.8 METs (9.8x resting), walking has 3.5 METs, cycling has 7.5 METs, and swimming has 8.0 METs. Higher MET values indicate more intense activities that burn more calories.
How accurate is the MET-based calorie calculation?
MET-based calculations provide a good estimate typically within +/-10-20% for most individuals. Accuracy depends on factors like fitness level, body composition, exercise efficiency, and actual intensity versus standard MET values. For precise measurements, lab-grade metabolic testing with VO2 analysis is needed. Our calculator uses the 2011 Compendium of Physical Activities MET values for accuracy.
Which activity burns the most calories per hour?
Jump rope has the highest MET value at 10.0, burning about 700 calories per hour for a 70 kg person. Running follows at 9.8 METs (686 cal/hr), then HIIT at 8.5 METs (595 cal/hr), swimming at 8.0 METs (560 cal/hr), and cycling at 7.5 METs (525 cal/hr). Walking at 3.5 METs burns about 245 cal/hr for the same person.
How many calories do I burn walking for 30 minutes?
A 70 kg person walking at a moderate pace (MET 3.5) for 30 minutes burns approximately 123 calories. The exact number varies based on your weight and walking pace. Heavier individuals burn more calories as the formula factors in body weight. Using our calculator, enter your weight, select walking, and set duration to get your personalized result.
How can I use calorie burn data for weight loss?
To lose weight, create a calorie deficit by burning more calories than you consume. One pound (0.45 kg) of body fat equals approximately 3,500 calories. For example, if you create a 500-calorie daily deficit through exercise and diet, you can lose about 1 pound per week. Use our calories burned calculator to track exercise calories and combine with a balanced diet.
Do I burn more calories running or cycling?
Running has a MET of 9.8 while cycling has a MET of 7.5, meaning running burns about 30% more calories per hour for the same person. A 70 kg person burns 686 cal/hr running versus 525 cal/hr cycling. However, cycling is lower impact and can be sustained longer, potentially burning more total calories over a longer workout session.
What is the difference between calories and kilocalories?
In nutrition and exercise science, the terms are used interchangeably but technically 1 kilocalorie (kcal) equals 1,000 calories. When we say 'calories burned' during exercise, we actually mean kilocalories. So 1 kcal = 1,000 small calories = 4.18 kilojoules (kJ). Our calculator reports results in kcal, which is the standard for exercise energy expenditure.
