How to Use a BMI Calculator: A Guide for Your Health Journey
Understanding your health and fitness just got easier with the BMI Calculator. BMI, or Body Mass Index, is a measure that helps you understand if you're in a healthy weight range. Here's a simple guide on how to use a BMI calculator.
What is BMI?
BMI is a screening tool that categorizes body weight into underweight, normal weight, overweight, and obese categories. This categorization is based on a calculation considering your height and weight.

The History of the BMI Calculator
The Body Mass Index (BMI) calculator, a tool used ubiquitously in the modern health and fitness world, has a history that dates back over a century. Contrary to common belief, the BMI calculator was not initially developed for health-related purposes. Its roots can be traced back to the early 19th century and to a Belgian mathematician named Adolphe Quetelet.
Quetelet was not a physician; he was a sociologist and statistician. In the 1830s, he embarked on a quest to define the characteristics of the "average man" for his social physics studies. Quetelet's Index, later known as the Body Mass Index, emerged from this endeavor. He developed this index as part of his broader work on anthropometry – the study of the human body's measurements.
The BMI formula is surprisingly simple: it is the individual’s body weight in kilograms divided by the square of their height in meters. Despite its simplicity, this formula wasn't widely used in the medical community until well into the 20th century.
A major turning point came in the mid-1900s, when Ancel Keys, an American physiologist, re-introduced the formula in his study. Keys was researching obesity and needed a straightforward, reliable method for studying the body fat percentages of different populations. In his 1972 paper titled "Indices of Relative Weight and Obesity," Keys deemed Quetelet's Index as the most appropriate. He renamed it the Body Mass Index.
The adoption of BMI skyrocketed after Keys’ endorsement. It became a standard tool to quickly assess an individual's body fat based on their height and weight. Its simplicity and cost-effectiveness made it a popular choice in public health surveys, clinical settings, and personal health assessments.
However, the BMI calculator is not without its controversies. Critics argue that it oversimplifies health assessments, as it does not differentiate between muscle and fat mass, nor does it account for distribution of fat, bone density, or racial and gender differences. Despite these criticisms, the BMI calculator remains a prevalent tool due to its ease of use and its ability to offer a quick, general assessment of a person’s health in relation to their weight.
In recent years, technology has further popularized the BMI calculator. It is now widely accessible online and is incorporated into various health and fitness apps, making it easier than ever for individuals to calculate and understand their BMI.
