Understanding BMI Basics
What is Body Mass Index (BMI)?
Body Mass Index (BMI) is a simple numerical value derived from an individual's weight and height. It's used as a screening tool to identify possible weight problems for adults. While it doesn't measure body fat directly, research has shown that BMI is moderately correlated with more direct measures of body fat.
The Formula:
Imperial: BMI = 703 × weight (lbs) / [height (in)]²
