What is a Calories Burned Calculator?
A calories burned calculator estimates the energy expenditure during physical activity using MET (Metabolic Equivalent of Task) values. MET represents the ratio of exercise intensity to resting metabolic rate — a MET of 8 means the activity burns 8 times more calories than sitting still. The formula is: Calories = MET × weight (kg) × duration (hours).

Frequently Asked Questions
How accurate is the MET-based calorie estimate?
MET-based estimates are reasonably accurate for population averages but can vary ±20% for individuals due to fitness level, age, and exercise efficiency. Heavier people burn more calories for the same activity, which this calculator accounts for.
Does this include calories burned at rest?
Yes — MET values include resting metabolic rate. A MET of 1.0 equals resting, so the calories shown represent total expenditure during the activity, not just the extra calories above rest.
Which exercise burns the most calories?
High-intensity activities like running, jump rope, HIIT, and stair climbing have the highest MET values (8–12+) and burn the most calories per minute. However, lower-intensity activities done for longer durations can also accumulate significant calorie burn.
