Frequently Asked Questions
What is a healthy BMI range?
A BMI between 18.5 and 24.9 is generally considered a normal weight range for most adults, though this varies by individual factors.
Is BMI an accurate measure of health?
BMI is a useful general screening tool, but it doesn't account for muscle mass, bone density, or body composition, so it isn't a complete picture of individual health. Consult a healthcare professional for personalized guidance.
What formula is used for imperial units?
BMI = (weight in pounds / (height in inches)²) × 703.
