BAI calculator with BMI comparison
This is an interesting real-life application of graphs of functions. For background on this, see New measure of obesity – body adiposity index (BAI).
Enter your age, gender, height, weight, and hip circumference ("at the level of the maximum extension of the buttocks posteriorly in a horizontal plane") below. (Some typical values are given.)
[If you still think in feet, pounds and inches, you can convert your measurements to metric here.]
