Compare Devine, Robinson and Miller adult reference-weight formulas and a separate BMI screening interval without prescribing a target.
A quick decision brief for this specific tool
Adult height at least 5 ft (152.4 cm) and the published male-constant or female-constant historical formula set
Separate Devine, Robinson and Miller estimates, their observed span, and a separately labeled adult BMI screening interval
Applies each historical height-based formula independently and preserves disagreement; it does not average the equations into an “ideal” or target weight
Choose your path
Compare three historical adult height-based reference-weight formulas and a separate BMI screening interval without prescribing a target, averaging unlike methods or enabling clinical dosing.
See formula disagreement instead of one authoritative “ideal.”
Enter adult height and the published constant set, then inspect each estimate and span.
Understands that the range is disagreement among models, not a recommended goal.
Avoid interpreting height-only formulas as body composition or health.
Review the BMI/formula limitations and use qualified assessment if needed.
Does not change weight solely from the calculator.
Avoid applying a generic web equation to medication or ventilation.
Use the exact clinical protocol, current measurements and qualified guidance outside the tool.
Never copies the result into a clinical dose.
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.
Tools you might need next
Calculate adult BMI from metric or imperial height and weight. See CDC screening categories, formula steps, and limitations without treating BMI as a diagnosis.
Estimate adult body-fat percentage with a sex-specific U.S. Navy circumference equation, explicit measurement guidance, unit conversion, and non-diagnostic limitations.
Compare adult BMR equations and a selected activity-multiplier TDEE scenario without generating calorie, macro, or meal prescriptions.
Devine, Robinson and Miller use different published constants and coefficients for inches above 5 ft. The calculator shows each result and their span instead of treating one or their average as a personal ideal.
reference kg = published base constant + coefficient × inches above 60Published discussions note that many historical formulas are recommended only above 5 ft. The calculator therefore rejects heights below 152.4 cm rather than extrapolating an unsupported line.
The 18.5–24.9 adult BMI interval is calculated independently from height. CDC describes BMI as one screening measure to consider with exam, laboratory, behavior and other factors—not a diagnosis or target.
screening weight = BMI × height² (m²)Updated: August 2026
An adult selects the published male constants and records each historical estimate plus the observed span, without turning the span into a target.
An athlete sees that height-only formulas and BMI do not measure muscle, fat, bone, health history or individualized goals and seeks appropriate assessment.
A pharmacist or clinician does not copy a web result into medication or ventilation dosing and instead follows the exact current clinical protocol.
Keep Devine, Robinson and Miller separate. Their disagreement demonstrates model dependence and does not define a personal target.
Use the exact clinical protocol and qualified guidance for dosing. BMI and height-only formulas do not replace a full health assessment.
Compare three historical adult height-based reference formulas and a separately labeled BMI screening interval. The tool preserves model disagreement and does not prescribe an ideal, goal, dose, or diagnosis.
