Calories Burned Calculator

Estimate how many calories you burn during various physical activities.

Pro Efficiency

Keep a consistent pace to maintain your targeted intensity. Small increases in MET can significantly impact your daily deficit.

How Are Calories Burned Calculated?

Calculating calorie expenditure is essential for managing weight and tracking fitness progress. This calculator uses MET (Metabolic Equivalent of Task) values to estimate energy expenditure. One MET is defined as the amount of oxygen consumed while sitting at rest and is equal to 3.5 ml O2 per kg body weight x min.

Understanding METs

MET stands for Metabolic Equivalent of Task. It represents the intensity of an activity relative to sitting quietly. For example, an activity with a MET of 5 means you are burning 5 times more calories than you would at rest. Higher intensity activities like running have higher MET values.

Intensity Matters

Higher MET values indicate more vigorous activity. Transitioning from moderate to brisk walking can significantly increase your efficiency.

The Calculation

Calories = MET × Weight (kg) × Duration (hours)

To find the total calories burned, we multiply the intensity of the activity (MET) by your body weight and the time spent performing that activity. This provides a standardized estimate suitable for most individuals.

Activity Comparisons

Walking (Brisk)

A 70kg person walking briskly (MET 5.0) for 30 minutes burns approximately 175 calories.

Running (12 km/h)

A 70kg person running at a vigorous pace (MET 12.5) for 30 minutes burns approximately 438 calories.
