Frequently Asked Questions
What is BMI and how is it calculated?
BMI (Body Mass Index) is a measure of body fat based on height and weight. It is calculated by dividing weight in kilograms by the square of height in metres (kg/m²). A BMI between 18.5 and 24.9 is considered normal.
Is BMI accurate for everyone?
BMI is a useful screening tool but does not account for muscle mass, age, or fat distribution. Athletes and older adults may get misleading results. Always consult a healthcare professional for a full health assessment.
What BMI categories does this calculator use?
The calculator uses WHO standard categories: Underweight (below 18.5), Normal weight (18.5–24.9), Overweight (25–29.9), and Obese (30 and above).
Does the BMI calculator support imperial units?
Yes. You can switch between metric (kg/cm) and imperial (lbs/inches/feet) units at any time.
