How do I calculate the number of calories burned on a treadmill?

To calculate the number of calories burned on a treadmill, you can use the following steps:

Determine your weight in kilograms (kg): If you know your weight in pounds (lbs), you can convert it to kilograms by dividing it by 2.2046. For example, if your weight is 150 lbs, the calculation would be 150 / 2.2046 = 68.04 kg.

Measure the duration of your treadmill workout: Note the amount of time you spend on the treadmill in minutes. For example, if you run for 30 minutes, your duration would be 30 minutes.

Find the MET value for your activity: MET (Metabolic Equivalent of Task) is a value that represents the energy expenditure of an activity compared to the resting metabolic rate. The MET value for treadmill activities depends on the intensity of your workout. Here are some common MET values for different treadmill activities:

Walking at a moderate pace (3.5 mph or 5.6 km/h): 3.8 METs

Running at a moderate pace (5 mph or 8 km/h): 8.3 METs

Running at a vigorous pace (8 mph or 12.9 km/h): 11.8 METs

Calculate the calories burned: Use the following formula to calculate the calories burned:

Calories burned = MET value * weight in kg * duration in hours

For example, if you weigh 68.04 kg, your duration is 0.5 hours (30 minutes converted to hours), and you are running at a moderate pace (8.3 METs), the calculation would be:

Calories burned = 8.3 * 68.04 * 0.5 = 282.35 calories

Keep in mind that these calculations are estimates, and individual variations such as fitness level, body composition, and efficiency of movement can affect the actual calorie expenditure. Additionally, treadmills with built-in heart rate monitors or other advanced features may provide more accurate calorie burn data based on your specific profile and heart rate measurements.
