Using the Kilogram IBW formula Men: IBW = 50 + 2.3 × (Height in inches − 60). If a male patient is 70 inches tall, what is IBW in kilograms?

This question uses the male IBW formula: start with 50 kg and add 2.3 kg for each inch over 60 inches. A height of 70 inches is 10 inches over 60, so the increase is 10 × 2.3 = 23 kg. Add that to 50 kg to get 73 kg. So the ideal body weight is 73 kilograms. For reference, the female version starts at 45.5 kg and also adds 2.3 kg per inch over 60.
