How to Use This Tool

  1. Select your activity from the list.
  2. Enter your weight and duration of exercise.
  3. Click Calculate for estimated calories burned.

The MET Formula

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

MET (Metabolic Equivalent of Task) represents the energy cost of an activity relative to resting metabolism — an activity with a MET of 8 burns roughly 8 times as many calories as sitting quietly.

Why This Is an Estimate

MET values represent averages across many individuals and don't account for your specific fitness level, exact intensity, body composition, or metabolic efficiency — actual calorie burn can vary meaningfully from person to person even doing the identical activity.

Using This for Weight Management

Calories burned estimates are useful context for weight management, but for precise tracking, consider that food calorie counts also carry estimation error — focus on consistent trends over time rather than treating any single number as exact.

Frequently Asked Questions

What is a MET value?

MET (Metabolic Equivalent of Task) measures how many times more energy an activity requires compared to resting — a MET of 1 equals resting metabolism, and a MET of 8 means the activity burns roughly 8 times as many calories as sitting still.

Why might my fitness tracker show a different calorie count?

Fitness trackers often use additional data like heart rate, which can produce different estimates than standard MET-based calculations — both are estimates, and actual calorie burn varies by individual metabolism and exact intensity.
