Calculate adult BMI from metric or imperial height and weight. See CDC screening categories, formula steps, and limitations without treating BMI as a diagnosis.

Compare Devine, Robinson and Miller adult reference-weight formulas and a separate BMI screening interval without prescribing a target.

Convert a user-selected energy total and carbohydrate, protein, and fat percentages into calories and grams with adult AMDR context.

Estimate adult basal metabolic rate with Mifflin–St Jeor, revised Harris–Benedict, or Katch–McArdle, plus a clearly labeled activity-multiplier TDEE scenario.

Estimate adult body-fat percentage with a sex-specific U.S. Navy circumference equation, explicit measurement guidance, unit conversion, and non-diagnostic limitations.
