Understanding the BMI Formula
The Body Index Calculator uses a standard BMI formula used worldwide.
Step 1: Convert Height to Meters
Since height is entered in centimeters, it is first converted into meters:
hm=100hcm
Where:
- hm = height in meters
- hcm = height in centimeters
Step 2: BMI Calculation Formula
BMI=Height2Weight
Where:
- Weight = in kilograms
- Height = in meters
BMI Categories Explained
Once your BMI is calculated, it falls into one of four categories:
1. Underweight
BMI less than 18.5
May indicate insufficient body weight or nutritional deficiency.
2. Normal Weight
BMI between 18.5 and 24.9
Considered a healthy range for most adults.
3. Overweight
BMI between 25 and 29.9
May indicate excess body weight.
4. Obese
BMI 30 and above
Associated with higher risk of health problems.
Example Calculation
Let’s understand how BMI is calculated with a real example.
Given:
- Weight = 70 kg
- Height = 170 cm
Step 1: Convert Height
Height in meters = 170 ÷ 100 = 1.7 m
Step 2: Apply Formula
BMI = 70 ÷ (1.7 × 1.7)
Step 3: Solve
BMI = 70 ÷ 2.89 = 24.22
Result:
- BMI Value: 24.22
- Category: Normal Weight
