*What is BMI?*

Body Mass Index (BMI) is a number calculated from a person's weight and
height. BMI is a fairly reliable indicator of body fatness for most

A graph of body mass index as a function of body mass and body height is
shown above. The dashed lines represent subdivisions within a major class.
For instance the "Underweight" classification is further divided into
"severe", "moderate", and "mild" subclasses.^[1]

The *body mass index* (*BMI*), or *Quetelet index*, is a measure for human
body shape based on an individual's mass and height. It was devised between
1830 and 1850 by the Belgian polymath Adolphe Quetelet during the course of
developing "social physics".^[2] Body mass index is defined as the
individual's body mass divided by the square of their height. The formulae
universally used in medicine produce a unit of measure of kg/m^2. BMI can
also be determined using a BMI chart,^[3] which displays BMI as a function
of mass (horizontal axis) and height (vertical axis) using contour lines
for different values of BMI or colors for different BMI categories.

^† The factor for UK/US units is more precisely 703.06957964, but that
level of precision is not meaningful for this calculation. To work from
stones and pounds first multiply the stones by 14 then add the pounds to
give the whole mass in pounds; to work from feet and inches first multiply
the feet by 12 then add the inches to give the whole height in inches.
