FAQ
Frequently asked questions
What is BMI?
BMI stands for Body Mass Index. It is a value derived from the mass (weight) and height of a person. It is widely used as a general indicator of whether a person has a healthy body weight for their height.
How is BMI calculated in metric units?
The formula is weight in kilograms divided by height in meters squared (kg/m²). Our calculator automatically converts your height in centimeters into meters to perform this calculation.
What is a healthy BMI range?
According to the World Health Organization (WHO), a normal and healthy BMI range for adults is between 18.5 and 24.9.
Is BMI accurate for everyone?
No. BMI is a general estimate. It does not distinguish between muscle mass and fat mass, which means highly muscular athletes might have a high BMI without being unhealthy.
Should I use BMI as medical advice?
No. BMI is just a screening tool. You should always consult a doctor or a qualified healthcare professional for a comprehensive health assessment.
Are the height and weight I enter kept private?
Yes. Your numbers are used only in your browser to calculate BMI. Nothing is uploaded, saved, or shared with any server.
