What is BMI?

BMI, or Body Mass Index is a measure of someone's weight in relation to height. To calculate one's BMI, multiply one's weight in pounds and divide that by the square of one's height in inches. People considered to be overweight have a BMI greater than 25. People considered to be obese have a BMI greater than 30. BMI is a reliable indicator of weight related health issues. It uses a mathematical formula using height and weight to calculate a number that is then pugged into a chart that indicates whether someone is underweight, normal, at risk for overweight, or overweight compared to age.

BMI Calculations (English Formula)

[Weight in lbs/(height in inches)squared] X 703

Example: Mr. Bowen is 215 lbs and his height is 72 inches
and his age is 28
[215 lbs/ (72inches)squred] X 703 = 29.1

Mr. Bowen's BMI = 29
Plug the number 29 in the chart with the age 28, and you find what category Mr. Bowen is considered by percentile. Mr. Bowen falls into the 95th percentile which is considered to be overweight.

For class purposes the overweight and obese categories will be called, "Needs Improvement." This will make it so students do not feel embarrassed. Also, when the calculations are done in class, students will have rights to complete privacy. The teacher will be the only person to see their BMI's.
