What This Calculator Does
The Calories Burned Cycling Calculator estimates how much energy you expend on a bike ride based on three inputs: your body weight, how long you ride, and how fast you go. It uses the MET (Metabolic Equivalent of Task) system, a standardized way of comparing the energy cost of physical activities developed from exercise physiology research.
How to Use It
Enter your body weight in kilograms, the duration of your ride in minutes, and select the speed category that best matches your effort. Faster, more intense cycling carries a higher MET value and therefore burns more calories. Click calculate to see total calories burned plus per-minute and per-hour breakdowns.
The Formula Explained
Calories burned are calculated as $$\text{kcal} = \text{MET} \times \text{weight (kg)} \times \text{hours}$$ One MET represents the energy used while sitting quietly (about 1 kcal per kg of body weight per hour). Leisurely cycling under 16 km/h is roughly 4 METs, while racing above 30 km/h reaches about 15.8 METs. We convert your minutes to hours (\(\text{minutes} \div 60\)) before multiplying.
Worked Example
A 70 kg rider cycles for 60 minutes at a moderate pace of 19–22 km/h (MET 8.0). That is $$8.0 \times 70 \times 1 \text{ hour} = 560 \text{ kcal}$$ The same rider going for just 30 minutes would burn \(8.0 \times 70 \times 0.5 = 280\) kcal.
FAQ
Why does speed matter so much? Higher speeds require dramatically more power to overcome air resistance, so the MET value rises sharply, increasing calorie burn.
Is this exact? MET-based estimates are good approximations but real burn varies with fitness, terrain, wind, bike type and body composition. Use it as a guide, not a precise measurement.
What if I weigh in pounds? Divide your weight in pounds by 2.205 to get kilograms before entering it.
