What is BMI and How Is It Measured?

The BMI calculator is a quick and easy tool that helps you estimate your body fat based on height and weight. BMI, or Body Mass Index, is a number derived from your weight in kilograms divided by your height in meters squared.

While the BMI calculator is not a perfect measurement, it is a widely used health indicator. A high BMI can be an early sign of weight-related health issues like high blood pressure or diabetes.

BMI Formula
