Calculating body mass index (BMI) by hand is a fundamental skill that is useful in various contexts. BMI is a measure of body fat based on height and weight, widely used by healthcare professionals to screen for weight-related health risks.
It is relevant because it provides an initial assessment of a person’s weight status, helping to identify individuals at risk of developing obesity-related diseases. BMI is simple to calculate and can be used to track changes in body composition over time. The formula was developed by Adolphe Quetelet in the 19th century and has since become a cornerstone of anthropometric measurements.
