About the Ideal Weight tool
Shows Devine, Hamwi, Robinson and Miller ideal-weight estimates plus the 18.5–24.9 BMI band for your height, in kg or ft+in input.
The formulas disagree because they came from different clinical questions — reading the whole range instead of one number is the medically realistic answer.
