Cycling Calorie Burn Calculator Formula

Understand the math behind the cycling calorie burn calculator. Each variable explained with a worked example.

Formulas Used

Calories Burned

calories = round(met * weight_kg * duration_hr)

Calories per Hour

calories_per_hour = round(met * weight_kg)

Distance Covered

distance = round(speed_mph * duration_hr * 100) / 100

MET Value

met_display = round(met * 10) / 10

How It Works

How Cycling Calorie Burn Is Estimated

Formula

Calories = MET x Weight (kg) x Duration (hours)

The MET for cycling depends on intensity/speed. A simplified model:

MET = 3.5 + 0.45 x Speed (mph)

This gives approximately MET 6.8 at 10 mph (leisure) and MET 10.6 at 16 mph (vigorous).

Factors

Actual burn depends on terrain, wind, bike type, and rider efficiency. Hills and headwinds increase calorie burn significantly.

Worked Example

A 160 lb cyclist rides at 14 mph for 60 minutes.

weight_lbs = 160speed_mph = 14duration_min = 60
  1. 01Weight = 160 * 0.4536 = 72.57 kg
  2. 02Duration = 60 / 60 = 1 hour
  3. 03MET = 3.5 + 0.45 * 14 = 9.8
  4. 04Calories = 9.8 * 72.57 * 1 = 711 kcal
  5. 05Distance = 14 * 1 = 14 miles
