How to Use the Anorexic BMI Calculator

Body Mass Index (BMI) is sometimes employed for the purpose of general assessment for weight issues but appears to provide evidence for health issues in low values of BMI. This tool for the calculation for an anorexic BMI is a screening tool for the purpose of establishing low BMI categories that require health attention. This calculator is not diagnosing eating disorders or illnesses. However, it is pointing out instances that would normally be considered as being severely underweight based on BMI. It is important to consult an appropriate medical expert if one discovers that their BMI is low. Its main aim is awareness and early identification, and in no way involves any sort of self-evaluation.

How to Use

1. Select Your Measurement System

You can choose to have all the measurements in either metric units (kilograms and centimeters) or US units (in pounds, feet, and inches).

2. Enter Your Age and Gender

In interpreting BMI results, age and gender form a basis, since the health consideration may differ among these groups.

3. Input Height and Weight

Please enter your correct height and weight as accurately as possible. Tiny variations may drastically alter the BMI when at lower ranges.

4. Calculate Your BMI

BMI = weight (kg) ÷ height² (m²)
