A Body Mass Index (BMI) Measure is an index measure based on body mass divided by the square of the body height.
- AKA: Quetelet Index.
- Context:
- Example(s):
- $\mathrm{BMI} = \dfrac{\text{weight}_\text{kg}}{{\text{height}_\text{m}}^2}$ (BMI mathematical for the metric units system)
- $\mathrm{BMI} = \dfrac{\text{weight}_\text{lb}}{{\text{height}_\text{in}}^2}\times 703$ (BMI mathematical for the metric units system)

- The BMI is a convenient rule of thumb used to broadly categorize a person as underweight, normal weight, overweight, or obese based on tissue mass (muscle, fat, and bone) and height. Major adult BMI classifications are underweight (under 18.5 kg/m2), normal weight (18.5 to 24.9), overweight (25 to 29.9), and obese (30 or more).[1] When used to predict an individual's health, rather than as a statistical measurement for groups, the BMI has limitations that can make it less useful than some of the alternatives, especially when applied to individuals with abdominal obesity, short stature, or unusually high muscle mass.
BMIs under 20 and over 25 have been associated with higher all-cause mortality, with the risk increasing with distance from the 20–25 range.
