Calories burned in a day is a crucial metric for those who are conscious of their fitness and health. This calculator will help you estimate the number of calories you burn daily, considering factors like your weight, age, gender, and activity level.

Formula: The formula used to calculate daily calorie burn differs for men and women. For men, the formula is: Calories Burned = 88.362 + (13.397 * weight in kg) + (4.799 * age in years) + (5.677 * activity level)

For women, the formula is: Calories Burned = 447.593 + (9.247 * weight in kg) + (3.098 * age in years) + (4.330 * activity level)

How to Use: To use the calculator, simply enter your weight in kilograms, age in years, select your gender, and choose your activity level. Click the “Calculate” button, and the estimated daily calorie burn will be displayed.
