What this calculator does
This tool calculates adjusted body weight, which adjusts for the difference between actual weight and ideal body weight. It is sometimes used in clinical formulas when a person weighs more than their ideal body weight.
What your result means
The result is in kilograms. It is a reference value used in certain medical calculations (e.g. some drug dosing). Your care team will use it when relevant; it is not a goal weight.
This is not medical advice. A healthcare provider should interpret results in your context.
