Frequently Asked Questions

What does BMI stand for?

BMI stands for Body Mass Index. It is a value derived from the mass (weight) and height of a person.

How is BMI calculated?

BMI is calculated by dividing a person's weight in kilograms by the square of their height in meters (kg/m²). If using pounds and inches, the formula is [weight (lb) / height (in)²] x 703.

What are the BMI categories?

The standard BMI categories for adults are: Underweight (BMI < 18.5), Normal weight (18.5 ≤ BMI < 25), Overweight (25 ≤ BMI < 30), and Obesity (BMI ≥ 30).

Is BMI a reliable health indicator?

BMI is a useful screening tool but not a diagnostic tool. It does not measure body fat directly and does not account for factors like muscle mass, bone density, overall body composition, and ethnic differences. It should be used as one of several tools to assess health status. Consult a healthcare provider for a comprehensive health assessment.

Can children use this BMI calculator?

This calculator is intended for adults (20 years and older). BMI interpretation for children and adolescents is different and requires using growth charts specific to age and sex.
