What is BMI (Body Mass Index)?

Body Mass Index (BMI) is a numerical value derived from your height and weight. It is widely used by healthcare professionals to estimate whether a person has a healthy body weight for their height.

Although BMI does not directly measure body fat, it provides a useful screening tool for categorizing weight status.

BMI is commonly classified into four categories:

  • Underweight: BMI less than 18.5
  • Normal weight: BMI 18.5 – 24.9
  • Overweight: BMI 25 – 29.9
  • Obese: BMI 30 or higher

These categories help individuals understand whether they may need to adjust their lifestyle or diet habits.

How BMI is Calculated

The BMI formula used for this calculator is:

BMI = (Weight in Pounds / (Height in inches × Height in inches)) × 703

This formula is widely used in the United States and is recommended by health organizations like NHLBI (National Heart, Lung, and Blood Institute).

The calculator automatically performs this formula in the background, saving you time and effort.
