Compute my Body Mass Index (BMI) on-line calculator

Abstract: This is the only Body Mass Index caculator which can use either kilos/cm or pounds/feet/inches and which gives accurate data also for children. Body Mass Index is a code which indicates if you are underweight, normal or overweight, and can predict your life expectancy based on body shape and build.

What is my Body Mass Index (BMI) and what is normal body weight for my height? Which values of BMI indicate Anorexia?

Answer:

Do you weigh too much or too little? If you are over 15 years old, you can determine this by computing your Body Mass Index (BMI). BMI is computed by taking your weight in kilograms, and dividing by the square of your height in meters. Lower down on the page, interpretation of the Body Mass Index for children is described.
