How it works
This cycling calories calculator estimates how much energy you burned on a ride from your bodyweight, the time you spent riding, and the intensity expressed as a MET value. It uses the standard metabolic equation that underpins most exercise calorie estimates, giving you a reliable ballpark for planning nutrition, managing weight, or simply understanding what a ride cost you. MET, short for metabolic equivalent of task, rates how hard an activity is compared with sitting quietly. Gentle cycling sits around four METs, a steady moderate ride around eight, and hard, fast riding ten or more. Because the equation also scales with bodyweight, a heavier rider burns more than a lighter one over the same ride, which is why the calculator asks for your weight and lets you choose an intensity that matches how hard you actually rode. The formula works because energy use is closely tied to oxygen consumption, and the MET value, bodyweight, and duration together estimate the oxygen you burned, which converts to kilocalories at a known rate. Cyclists use this to plan an energy deficit for fat loss, to replace fuel after long rides so they recover well, and to compare the cost of easy spins against hard efforts. Remember it is an estimate: real burn shifts with wind, terrain, and efficiency, so treat the number as a well-founded guide rather than a precise measurement.
calories = MET × 3.5 × weight (kg) ÷ 200 × duration (min)
This is the standard MET equation for energy expenditure. The MET value states how many times more oxygen an activity uses than rest, and multiplying it by 3.5 gives millilitres of oxygen per kilogram per minute. Scaling by bodyweight converts that to total oxygen use, and dividing by 200 turns litres of oxygen into kilocalories, since roughly five kilocalories are released per litre of oxygen. Multiplying by the ride's minutes yields the total calories burned.

Frequently asked questions
What MET value should I use for my ride?
Choose the MET that matches how hard you rode. Light, leisurely cycling under about 16 km/h is roughly four METs, a moderate effort around 19 to 22 km/h is close to eight, and vigorous riding above 22 km/h ranges from ten upward, with racing higher still. Mountain biking and strong headwinds raise the figure. Pick the closest match to your average effort, leaning higher for harder rides and lower for gentle ones.
Why does the formula divide by 200?
The MET equation first estimates the oxygen your body consumed, in millilitres per minute, from the MET value, the constant 3.5, and your bodyweight. Dividing by 200 converts that oxygen use into kilocalories, because burning one litre of oxygen releases about five kilocalories and the arithmetic of the units works out to a division by two hundred. It is simply the conversion factor that turns oxygen consumption into the energy figure you want.
How accurate is the MET method for cycling?
It gives a good estimate but not a precise measurement. Real energy use on a bike varies with wind, gradient, road surface, riding position, and mechanical efficiency, none of which a single MET value captures. Two riders of the same weight at the same average speed can burn different amounts. Treat the result as a planning guide, and if you want more accuracy, a power meter measuring your actual work output is the gold standard.
Does bodyweight really affect cycling calories?
Yes, though its effect is smaller on the flat than in running, because the bike supports your weight. Still, a heavier rider burns more energy overall, especially when climbing or accelerating, which is why the equation scales with bodyweight. Entering your accurate weight keeps the estimate realistic. On long climbs the difference grows, since lifting extra mass against gravity is where bodyweight most strongly increases the energy a ride demands.
Is a burned calorie the same as a food calorie?
Yes. The calories this tool reports are kilocalories, the same unit shown on food labels, even though everyday language just calls them calories. So a result of 672 means 672 kilocalories, directly comparable to the energy listed on your food packaging. This lets you weigh what you burned against what you eat without any conversion, which is exactly what you need when planning a deficit for weight loss or refuelling after a hard ride.
