Step-by-step BMI calculation is a health assessment tool that evaluates body weight in relation to height. For instance, a 165-centimeter person weighing 60 kilograms would calculate their BMI by dividing their weight (60 kg) by their height in meters (1.65 m) squared, which equals 22.03 — indicating a healthy weight range.
Determining BMI has significant relevance in healthcare, aiding in early detection of potential weight concerns and associated health risks. Its widespread use is attributed to a landmark study published in 1972 by Ancel Keys, who established BMI as a reliable indicator for assessing body weight.
