What Is the Running Calorie Calculator?
This tool estimates how many calories you burn while running, based on your body weight, running speed and how long you run. It uses the widely accepted MET (Metabolic Equivalent of Task) method, the same approach used in exercise physiology research. Because heavier bodies and faster speeds require more energy, the result is personalised to your inputs rather than a one-size-fits-all number.
How to Use It
Enter your body weight in kilograms, the total time you ran in minutes, and your average running speed in kilometres per hour. The calculator automatically selects the appropriate MET value for that speed and returns total calories, your pace in minutes per kilometre, and a calories-per-minute figure.
The Formula Explained
The core equation is: $$\text{Calories} = \frac{\text{MET} \times 3.5 \times \text{weight (kg)}}{200} \times \text{minutes}$$. The number 3.5 represents resting oxygen consumption (ml/kg/min), and dividing by 200 converts oxygen use into kilocalories. The MET value scales with intensity — a gentle jog might be around 8 METs, while a fast 16 km/h run is close to 13 METs.
Worked Example
A 70 kg runner running at 10 km/h (a 6:00 min/km pace) for 30 minutes uses a MET of 9.8. $$\text{Calories} = 9.8 \times 3.5 \times 70 \div 200 \times 30 = 360.15 \text{ kcal}$$ That works out to about 12 calories per minute.
FAQ
Is this estimate exact? No calorie calculator is perfectly precise. MET-based estimates are accurate for general planning but real burn varies with fitness, terrain, wind and metabolism.
Does it count my resting calories? The MET formula includes total energy during the activity. To find calories burned above rest, subtract roughly 1 MET worth of energy.
What if I run in mph? Convert miles per hour to km/h by multiplying by \(1.609\) before entering your speed.
