What this calculator does
Running burns substantial calories using MET values. Moderate pace (6 mph) is ~9.8 METs. A 150-lb person burns 300-400 calories in 30 minutes depending on pace.
How it works
Calories = METs × Weight (kg) × Duration (hours). MET values: 6 mph = 9.8, 7 mph = 11, 8 mph = 12.3.
Formula
Calories = (Minutes × MET × 3.5 × Weight kg) ÷ 200.
