BMI Formula Explained

The Body Mass Index is calculated using a simple scientific formula.

BMI Formula:

BMI=Weight (kg)Height (m)2BMI = \frac{Weight\,(kg)}{Height\,(m)^2}BMI=Height(m)2Weight(kg)​

Where:

  • Weight is measured in kilograms
  • Height is measured in meters

Since height is entered in centimeters in this calculator, it is first converted into meters:

Height (m)=Height (cm)100Height\,(m) = \frac{Height\,(cm)}{100}Height(m)=100Height(cm)​

Then BMI is calculated using the main formula.

BMI Categories Explained

Once BMI is calculated, it falls into one of four categories:

1. Underweight

BMI less than 18.5

  • May indicate insufficient nutrition
  • Health note: Consider healthy weight gain

2. Normal Weight

BMI between 18.5 and 24.9

  • Ideal and healthy range
  • Health note: Maintain current lifestyle

3. Overweight

BMI between 25 and 29.9

  • Slightly above healthy range
  • Health note: Balanced diet and exercise recommended

4. Obese

BMI 30 or above

  • Higher risk of health problems
  • Health note: Consult healthcare professional

Example Calculation

Let’s understand BMI with a real example.

Given:

  • Weight = 70 kg
  • Height = 170 cm
  • Gender = Male

Step 1: Convert Height

Height = 170 ÷ 100 = 1.7 meters

Step 2: Apply Formula

BMI=701.72BMI = \frac{70}{1.7^2}BMI=1.7270​

Step 3: Calculate

BMI≈24.22BMI \approx 24.22BMI≈24.22

Result:

  • BMI Value: 24.22
  • Category: Normal
  • Health Note: Healthy range. Keep it up (Male health tracking applied)

How Gender Affects the Result

While BMI formula remains the same for everyone, gender-based notes provide additional context:

Male Users

  • Focus on muscle mass and metabolism
  • Health notes encourage strength and fitness balance

Female Users

  • Focus on hormonal balance and body composition
  • Health notes include female-specific wellness reminders

This makes the tool slightly more personalized.
