Use health estimates as screening information
The BMI calculator divides adult body weight in kilograms by height in meters squared. BMI is a screening ratio rather than a direct measurement of body fat, diagnosis, or treatment recommendation. Age, muscle mass, pregnancy, and other individual factors can affect how a result should be interpreted.
- Use a recent measured height and weight in the units shown by the form.
- Adult BMI ranges should not be applied to children or teenagers without age-appropriate guidance.
- Discuss personal health questions with a qualified healthcare professional.
