Frequently Asked Questions
How does the calories burned calculator work?
The calories burned calculator uses MET (Metabolic Equivalent of Task) values to estimate energy expenditure. It takes into account your weight, gender, age, the type of activity performed, and duration. The calculator multiplies your weight by the MET value of the activity, then factors in duration and makes adjustments for gender and age to provide an estimate of calories burned.
What is a MET value?
MET (Metabolic Equivalent of Task) is a measure of the energy cost of physical activities. One MET is defined as the energy expended while sitting at rest, which is approximately 1 calorie per kilogram of body weight per hour. Activities with higher MET values burn more calories. For example, walking has a MET of about 3.5, while running can have a MET of 8-10 or higher depending on intensity.
How accurate is the calories burned estimate?
The calculator provides a reasonable estimate based on average energy expenditure, but individual results may vary. Factors such as fitness level, body composition, efficiency of movement, terrain, weather conditions, and individual metabolism can all affect actual calorie burn. For more precise measurements, wearable fitness devices that monitor heart rate can provide more personalized estimates.
Why does gender affect calories burned?
On average, men tend to burn more calories than women during the same activity due to differences in body composition. Men typically have more muscle mass and less body fat than women of the same weight, and muscle tissue uses more energy than fat tissue. The calculator applies a small adjustment factor to account for these average differences between biological males and females.
