Step-by-Step Guide to Calculate BMI

1. Measure Your Height:

   • Ensure you are barefoot and standing straight.
   • Use a tape measure or stadiometer to measure your height in centimeters (cm).

2. Measure Your Weight:

   • Use a digital or analog scale to measure your weight.
   • Ensure you are wearing minimal clothing and measure your weight in kilograms (kg).

3. Convert Height to Meters:

   • Since BMI requires height in meters, convert your height from centimeters to meters by dividing by 100.
   • For example, if your height is 170 cm, then Height in meters==100/170​=1.70 m.

4. Calculate BMI Using the Formula:

   • The formula for BMI is:
   • BMI=Weight in kilograms/(Height in meters)2
   • For example, if your weight is 70 kg and your height is 1.70 m:- BMI=70/(170)2​=70/2.89​≈24.22​

   1. Interpret Your BMI:

      • Use the following ranges to interpret your BMI:
        • Underweight: BMI < 18.5
        • Normal weight: 18.5 ≤ BMI < 24.9
        • Overweight: 25 ≤ BMI < 29.9
        • Obesity: BMI ≥ 30

5. Example Calculation

   Let’s say your height is 160 cm and your weight is 60 kg.

   1. Measure Your Height: 160 cm
   2. Measure Your Weight: 60 kg
   3. Convert Height to Meters: Height in meters=160/100​=1.60 m
   4. Calculate BMI:
   5. BMI=60/(1.60)2​=60/2.56​≈23.44
   6. Interpret Your BMI:
      • A BMI of 23.44 falls within the “Normal weight” range.
