Why can 24.96 show Healthy weight?

The adult healthy-weight category is 18.5 to below 25. The tool classifies the unrounded value, so rounding cannot change the category.

Does BMI measure body fat or health directly?

No. BMI does not directly measure body composition or establish an individual diagnosis. Muscle mass and other factors require context.
