How are running calories calculated?

The formula is: kcal = MET × weight_kg × duration_hours. MET (Metabolic Equivalent of Task) is a standard value assigned to each running pace from the Compendium of Physical Activities. A higher pace has a higher MET, meaning more calories burned per minute.

Why does body weight affect calories burned while running?

Heavier runners must move more mass against gravity with every stride. The MET formula multiplies directly by weight in kg, so a 90 kg runner burns about 50% more calories per mile than a 60 kg runner at the same pace.

How accurate is this calculator?

Estimates are within roughly ±15–25% of actual values. MET values are population averages and do not capture individual differences such as running efficiency, fitness level, terrain grade, wind, or body composition. Heart-rate-based devices may give different readings.

What is the difference between calculating by distance vs. by duration?

By duration: you enter time and the tool uses MET × weight × time. By distance: the tool derives duration from distance ÷ pace speed, then applies the same formula. Both modes give identical results when the inputs are consistent.

Does running speed or distance matter more for calorie burn?

Distance is the dominant factor. Running 5 miles at any pace burns roughly the same calories because faster running covers the distance in less time but at a proportionally higher MET. The difference between a 9 min/mile and 6 min/mile pace over the same distance is typically only 5–10%.

How many calories does running burn per mile?

A rough rule of thumb is approximately 80–110 kcal per mile for most adults, scaling with body weight. At 70 kg (154 lb), running a mile at any moderate pace burns about 90–100 kcal. This calculator shows the exact value for your weight and pace.
