The body mass index (BMI) is a special measurement used to determine whether your weight is healthy for your height. There are five classifications of BMI: Underweight (below 18.5), healthy (18.5-24.9), overweight (25.0-29.9), obese (30.0-39.9), and morbidly obese (more than 40).MI is calculated from a person's weight and height, regardless of gender. To calculate your BMI, divide your weight in pounds by your height in inches squared. Multiply that total by 703. Or, divide your weight in kilograms by your height in meters squared.
