The Calorie Calculator helps you estimate the number of calories you need to consume each day to maintain your current weight. Input your age, gender, weight, height, and activity level to calculate your daily calorie needs. The calculation is based on the Harris-Benedict equation, which is a widely used formula for estimating an individual’s basal metabolic rate (BMR) and total daily energy expenditure (TDEE).

The Food Energy Converter allows you to convert between calories (kcal) and joules (J). One calorie is equal to 4.184 joules. Enter a value in either field and click “Convert Energy” to see the equivalent value in the other unit.
