BMI is not body-fat percentage
Athletes, very muscular people, pregnant users, children, older adults, and people with medical conditions should not treat BMI as a full health diagnosis.
Best use

Use BMI as a quick screening number, then judge progress with waist size, energy, strength, and photos.

Good target

The middle of the healthy range is a reference point, not a command. Body composition matters more than chasing one exact number.

Formula

BMI = weight in kilograms divided by height in meters squared. The same result is shown for metric and imperial inputs.
