Calories Burned Calculator

Discover how many calories you're burning during workouts and daily activities

Tracking calories burned is essential for anyone serious about fitness or weight operation. Understanding your energy expenditure helps balance nutrition with exertion, making it easier to achieve pretensions like fat loss, muscle gain, or bettered abidance. Our calculator uses scientifically validated MET values to give dependable estimates grounded on your specific body criteria and exercise details.

How This Calculator Works

Our calculator uses the scientifically validated Metabolic Equivalent of Task (MET) system to estimate calorie expenditure. MET values represent the energy cost of physical activities as multiples of your resting metabolic rate.

Duration-Based Formula:

Calories = (hours × 60 + minutes) × MET × weight(kg) ÷ 60

Distance-Based Formula:

Calories = Distance(km) × MET × weight(kg)

The formulas account for your body weight, as heavier individuals burn more calories performing the same activity. The MET values we use come from the Compendium of Physical Activities, the most comprehensive reference for exercise energy expenditure.

Example Calculation

Duration Example: A 75kg person cycling for 45 minutes (MET=6.0):

(0 × 60 + 45) × 6.0 × 75 ÷ 60 = 45 × 6.0 × 1.25 = 337.5 kcal

Distance Example: A 68kg person running 8km at moderate pace (MET=8.3):

8 × 8.3 × 68 = 8 × 564.4 = 4,515.2 kcal

Factors Affecting Calorie Burn

While MET values provide excellent estimates, actual calorie expenditure can vary based on several personal factors:

Body Composition

Muscle tissue burns more calories at rest than fat tissue. Individuals with higher muscle mass will burn more calories during the same activity.

Exercise Intensity

Higher intensity exercise burns more calories per minute. For example, running burns nearly twice as many calories as walking the same distance.

Fitness Level

As you become fitter, your body becomes more efficient at performing activities, which may slightly reduce calorie burn for the same workout.

Age & Gender

Metabolism naturally slows with age. Men typically burn more calories than women during the same activity due to higher muscle mass.

Environmental Factors

Exercising in heat, cold, or at altitude increases calorie expenditure. Wind resistance and terrain also affect energy costs.

Afterburn Effect

High-intensity exercise creates an "afterburn" where your body continues to burn extra calories for hours after your workout ends.

Constantly Asked Questions

Which conditioning burn the utmost calories?

High- intensity conditioning like running, swimming, cycling, and HIIT exercises generally burn the utmost calories per hour. For illustration, a 155- pound person can burn 600- 700 calories per hour running at a moderate pace. Conditioning that engage multiple large muscle groups contemporaneously tend to be most effective for calorie burning.

How accurate is this calculator?

Our calculator provides estimates grounded on scientifically validated MET values. While it's generally accurate for utmost people, factual calorie burn can vary by 10- 20 grounded on individual factors like metabolism, fitness position, and body composition. For further precise measures, consider using a heart rate examiner with particular estimation.

Can I save my results?

Yes! Simply click the" Save to History" button below either calculator to store your last computation. We will keep your last 5 results for quick reference. Your history is stored locally in your cybersurfer and will not be saved on our waiters.

Do I need special outfit to track calories burned?

No special outfit is demanded to use our calculator. still, for more substantiated shadowing, fitness trackers and heart rate observers can give fresh delicacy by measuring your specific exertion situations during exercise. These bias are particularly useful for conditioning with variable intensity.

Why does weight affect calorie burn?

Heavier individualities burn further calories because moving more mass requires further energy. This is why body weight is a crucial element in our computations. For every exertion, a person importing 200 pounds will burn significantly further calories than someone importing 120 pounds performing the same exertion for the same duration.
