How BMI Is Calculated

BMI = weight (kg) / height² (m²)

Where:

  • BMI = Body Mass Index
  • weight = body weight in kilograms
  • height = body height in meters

Body Mass Index is a standard screening tool used to estimate body fat based on height and weight. This tool uses the standard metric formula to ensure accuracy. First, the calculator converts your height from centimeters to meters. Then, it squares your height measurement. Finally, it divides your weight in kilograms by that squared height number.

This calculation creates a standard ratio that allows healthcare providers to quickly assess if you fall within a healthy weight range or an underweight category that may require further medical evaluation.

What Your BMI Means

Your BMI score provides a numerical snapshot of how your weight relates to your height, categorizing you into specific health groups.

Key Scenarios

Very Severe Underweight (Below 15.0): A result here indicates significant health risks and potential malnutrition. You should seek immediate medical advice to discuss safe weight restoration.

Moderate to Mild Underweight (15.0 – 18.4): This range suggests you are below a healthy weight. Consult a doctor or dietitian to create a plan for gradual, healthy weight gain.

Normal Weight (18.5 – 24.9): Falling in this range generally suggests a healthy weight balance. Focus on maintaining nutritious eating habits and regular exercise.
