Healthy weight BMI calculator

Please note: BMI is a useful measurement of growth for most, but it is only an estimate and it is not able to differentiate between body fat and muscle mass. In addition, BMI may not be appropriate for people, particularly children, with certain health conditions such as some endocrine or genetic conditions. Speak to a health practitioner about your weight if you have any questions or concerns. This calculator is not appropriate for women who are more than 10 weeks pregnant or children under 2 years of age.
