FAQ
How is BMI calculated?
Weight (kg) divided by height (m) squared. The tool handles both metric and imperial inputs.
What is a healthy BMI range?
18.5-24.9 for most adults per WHO. Athletes and elderly individuals may need other measures.
Is BMI accurate for everyone?
It is a population screening tool, not a diagnosis — it does not distinguish muscle from fat.
