Note: One MET equals resting energy use (~1 kcal/kg/hour). The formula multiplies the activity's MET by your weight and duration. Real burn varies with fitness, intensity, and efficiency.

Calculation Method

This calculator estimates the calories you burn in any activity using its MET value, your body weight, and how long you do it — from running and cycling to housework and sport.

The Formula

Calories/min = MET × 3.5 × weight(kg) / 200

A MET (metabolic equivalent) is how many times harder an activity is than sitting at rest. Multiply calories per minute by your duration for the total.

Common MET Values

ActivityMETs
Walking (3 mph)3.5
Cycling (moderate)6–8
Running (6 mph)9.8
Swimming (moderate)5.8
Weight training3.5–6

Worked Example

A 70 kg person running at 9.8 METs for 30 minutes burns about 9.8 × 3.5 × 70 / 200 × 30 ≈ 360 calories.

MET values come from the Compendium of Physical Activities. Real burn varies with fitness, terrain, and effort — treat estimates as a guide.

Frequently Asked Questions

How are calories burned calculated?

Calories burned per minute = MET x 3.5 x body weight in kg / 200, multiplied by minutes. The MET (metabolic equivalent) reflects an activity's intensity — walking is about 3.5 METs, running 8–12.

How many calories do I burn in a workout?

It depends on the activity's intensity, your body weight, and duration. A 70 kg person doing a 6 MET activity for 30 minutes burns about 220 calories. Heavier people burn more for the same activity.

Are calorie-burn estimates accurate?

MET-based estimates are good population averages but individual burn varies with fitness, efficiency, and terrain. Use them as a guide and adjust based on your own results over time.
