About Calculator (Health)

A set of health calculators that run entirely in your browser. The BMI tab reports your Body Mass Index, weight category, healthy weight range, BMI Prime and Ponderal Index. The Calorie tab estimates your daily Calorie needs using the Mifflin-St Jeor equation and your activity level, with targets for losing or gaining weight, plus a food-energy converter (Calories, kJ, J). Estimates are for healthy adults and are not medical advice.
