The Body Mass Index (BMI) Calculator is a simple tool to assess whether your weight is in a healthy range relative to your height. It helps identify potential weight-related health risks.

Definition
Body Mass Index (BMI) is a numerical value derived from a person’s weight and height, used to classify weight status (underweight, normal, overweight, or obese).
Purpose
- Screens for weight categories that may lead to health problems.
- Helps assess risk for conditions like heart disease, diabetes, and hypertension.
- Provides a general guideline for weight management (not diagnostic).
Formula
BMI = Weight (kg) [Height (cm)]2
How to Use the BMI Calculator
- Enter your weight (in kg).
- Enter your height (in cm).
- Click Calculate to get your BMI value.
Example Calculation
If Weight = 70 kg and Height = 175 cm:
BMI = 70 / (175)2= 22.86
BMI = 70 [175]2 = 22.86
