Frequently Asked Questions
What is a healthy BMI range?
A BMI between 18.5 and 24.9 is considered normal or healthy weight for most adults.
Is BMI accurate for athletes?
BMI can overestimate body fat in people with high muscle mass. It is a general screening tool, not a medical diagnosis.
What is the difference between metric and imperial?
Metric uses centimeters and kilograms; imperial uses feet, inches, and pounds. Both inputs produce the same BMI result.
Should I see a doctor if my BMI is outside the normal range?
BMI is a general guideline. Consult a healthcare professional for a comprehensive health assessment.
