Devine, Robinson, Miller, and Hamwi are experience-based formulas proposed at different times. Their average and range can be a starting point for discussion, not a number you must reach.
Do not directly extrapolate these formulas below 152.4 cm (5 feet). They are not intended for children, adolescents, or pregnancy.
Height is converted to inches; n is the number of inches above 5 feet: n = height (cm) ÷ 2.54 − 60. The calculator uses Devine, Robinson, Miller, and Hamwi formulas and displays results to one decimal place.
No. Weight and health are also affected by age, body-fat distribution, muscle mass, medical conditions, medicines, lifestyle, and personal history. BMI is an adult screening reference, not a diagnosis.
Use the BMI reference range alongside weight trends, waist measurement, and advice from a clinician or registered dietitian. Seek professional advice for pregnancy, people under 18, or unintentional major weight change.
