BMI (Body Mass Index) is a measure of body fat based on height and weight. It provides a general indication of whether you are underweight, normal weight, overweight, or obese.

How is BMI calculated?

BMI is calculated by dividing weight in kilograms by height in meters squared. The formula is BMI = kg/m2. The tool handles unit conversions automatically.

Can I use pounds and feet?

Yes. Enter your height in feet and inches and weight in pounds. The tool converts to metric automatically and calculates your BMI.

What is a healthy BMI range?

A BMI between 18.5 and 24.9 is considered normal weight. Below 18.5 is underweight, 25-29.9 is overweight, and 30 or above is classified as obese.

Is BMI accurate for everyone?

BMI is a general screening tool and may not be accurate for athletes with high muscle mass, elderly individuals, or pregnant women. Consult a healthcare professional for comprehensive health assessment.
