Calculation Principles & Formulas
Ideal Body Weight (IBW) was originally developed for drug dosage calculations. Different formulas yield slightly different results based on height and gender. Here are the main medical formulas used in this tool:
- Devine Formula (1974): The most commonly used formula, often used for drug dosage calculations.
- Robinson Formula (1983): A modification of the Devine formula, aiming to improve accuracy for different heights.
- Miller Formula (1983): Also a modification of the Devine formula.
- Hamwi Formula (1964): Similar to Devine, but still used in some medical settings.
