Calculating Body Mass Index (BMI) manually involves determining the ratio of an individual’s weight to their height. For instance, a person weighing 70 kilograms and standing 1.75 meters tall would have a BMI of 22.86.
Assessing BMI manually is valuable for monitoring health, managing weight, and diagnosing conditions like obesity. Its origins trace back to the 19th century when Adolphe Quetelet, a Belgian statistician, developed the concept to categorize individuals based on their weight and height ratio.
