What Is BMI (Body Mass Index)?
BMI stands for Body Mass Index, a widely used measurement that compares your weight to your height. It helps determine whether your body weight is healthy, underweight, overweight, or obese.

Doctors, nutritionists, and fitness trainers often use BMI as a starting point to evaluate health conditions.

BMI Formula Explained
The calculator uses a standard BMI formula to determine your body mass index.
BMI Formula
BMI=Height(m)2Weight(kg)
Where:
- Weight is measured in kilograms (kg)
- Height is measured in meters (m)
Since height is entered in centimeters, it is converted into meters first:
Height(m)=100Height(cm)
BMI Categories and Health Status
Based on your BMI value, the calculator classifies your health into four main categories:
1. Underweight
BMI less than 18.5
- May indicate poor nutrition
- Risk of weakness or low energy
2. Normal Weight
BMI between 18.5 and 24.9
- Healthy body range
- Balanced fitness level
3. Overweight
BMI between 25 and 29.9
- Extra body weight
- May require lifestyle changes
4. Obese
BMI 30 and above
- Higher health risk
- Needs medical or fitness attention
Example Calculation
Let’s understand how BMI is calculated using a real-life example.
Given:
- Age = 25 years
- Weight = 70 kg
- Height = 170 cm
Step 1: Convert Height
Height in meters = 170 ÷ 100 = 1.7 m
Step 2: Apply BMI Formula
BMI=1.7270
Step 3: Solve
BMI=24.22
Result:
- BMI Value: 24.22
- Category: Normal Weight
- Health Status: Healthy
Importance of Knowing Your BMI
Understanding your BMI is important for several reasons:

3. Disease Prevention

Limitations of BMI
Although BMI is useful, it has some limitations:

For example, a muscular person may have a high BMI but still be very healthy.
