How the calorie burn is calculated

This calculator uses the standard MET (Metabolic Equivalent of Task) method, the same approach used by exercise physiologists and fitness trackers. The formula is:

Calories burned = MET × body weight (kg) × time (hours)

A MET is a unit of energy expenditure relative to resting. One MET is the energy you use sitting quietly — roughly 1 kcal per kilogram of body weight per hour. An activity rated at 8 METs burns energy about eight times faster than sitting still. Because the number of calories you burn scales directly with both your body weight and how long you ride, a heavier rider or a longer ride burns proportionally more.

Weight is converted to kilograms internally (1 lb = 0.45359237 kg) and duration to hours (minutes ÷ 60) before the multiplication, so you can enter your weight in pounds or kilograms and your ride time in minutes.

MET values for cycling

Cycling intensity is dominated by speed, because air resistance grows roughly with the square of velocity — so going faster costs disproportionately more energy. The values below come from the 2011 Compendium of Physical Activities, the reference source for MET coding:

  • Under 10 mph, light effort: ~4.0 METs
  • 10–11.9 mph, leisure: ~6.8 METs
  • 12–13.9 mph, moderate: ~8.0 METs
  • 14–15.9 mph, vigorous: ~10.0 METs
  • 16–19 mph, fast/racing: ~12.0 METs
  • 20+ mph, racing: ~15.8 METs
  • Mountain biking, general: ~8.5 METs
  • Stationary bike, moderate: ~7.0 METs

Worked example

Suppose you weigh 155 lb (70.3 kg) and ride for 45 minutes (0.75 hours) at a leisurely 6.8 METs. The calculation is 6.8 × 70.3 × 0.75 ≈ 359 calories. Ride the same 45 minutes vigorously at 10 METs and you burn 10 × 70.3 × 0.75 ≈ 527 calories — the higher intensity raises the burn by roughly 47%.

Why this estimate matters

Knowing your cycling calorie burn helps you match energy intake to output for weight management, plan fueling on longer rides, and compare cycling against other workouts on an equal footing. Since 3,500 calories is the commonly cited energy content of about one pound of body fat, a rider burning ~500 calories per session five days a week is spending roughly 2,500 calories weekly through exercise alone.

Frequently Asked Questions

What is the formula for calories burned biking?
Calories burned = MET × body weight in kilograms × time in hours. MET (Metabolic Equivalent of Task) measures exercise intensity relative to rest. For example, a 70 kg rider cycling at 8 METs for 1 hour burns 70 × 8 × 1 = 560 calories. This calculator converts pounds to kilograms and minutes to hours for you before applying the formula.
Does cycling speed change how many calories I burn?
Yes, substantially. Air resistance rises with roughly the square of speed, so effort climbs sharply as you ride faster. Cycling at 10–12 mph is about 6.8 METs, 12–14 mph about 8 METs, 14–16 mph about 10 METs, and racing above 20 mph can exceed 15.8 METs. Hills, headwinds, and carrying loads increase effort — and calorie burn — at any given speed.
Does a heavier person burn more calories cycling?
Yes. Because calories burned scale directly with body weight in the MET formula, a 200 lb rider burns about 29% more than a 155 lb rider over the same ride at the same intensity, all else equal. This is why the calculator asks for your weight rather than assuming an average.
How accurate is the MET method?
MET values are population averages, so your true burn can vary with fitness, pedaling efficiency, terrain, wind, and bike type. For most people the estimate is within roughly 10–15% of measured energy expenditure — reliable for planning and comparison. A power meter or lab metabolic cart gives a more individualized figure if you need precision.
