• For a 180 cm male example, the calculator converts height above 5 feet into inches and adds the Devine amount per inch.
• The BMI range then shows a broader weight span for the same height.

Formula and steps

The Devine estimate starts at 50 kg for males or 45.5 kg for females at 5 feet, then adds 2.3 kg per inch over 5 feet.

The formula line on the calculator page is there so the answer is not a mystery. Read it when you need to understand where the number came from.

How to read the answer
