BMI Calculator Online
A BMI (Body Mass Index) calculator is a valuable online tool used to estimate body fat content and assess whether an individual is at a healthy weight for their height. It's a simple, quick way to evaluate your body composition and potential health risks associated with being underweight, overweight, or obese.
What is BMI?
BMI is a measure that uses your height and weight to work out if your weight is healthy. It's calculated by dividing your weight in kilograms by the square of your height in meters. While BMI is not a perfect measure of body fat content or overall health, it's widely used as a quick and easy screening method.

Limitations of BMI

Who Should Use a BMI Calculator?
- Adults looking to assess their weight status
- Individuals starting a new health or fitness program
- Healthcare professionals for initial patient screening

FAQ
Is BMI calculation accurate for everyone?

How often should I calculate my BMI?
For most adults, calculating BMI once or twice a year is sufficient. If you're actively trying to lose or gain weight, you might want to check more frequently.
