My Health Tools: BMI Calculator

WHAT'S MY BMI? WEIGHT: Pounds Kilos HEIGHT: Inches Meters Underweight = < 18.5 BMI Normal = 18.5 - 24.9 BMI Overweight = 25.0 - 29.9 BMI Obesity - Class I = 30 - 34.9 BMI Obesity - Class II = 35 - 39.9 BMI Obesity - Class III = > 40 BMI Body Mass Index (BMI) describes relative weight for height. It approximates total body fat. The NHLBI (National Heart, Lung, and Blood Institute) obesity guidelines propose that health professionals use Body Mass Index (BMI) to assess patients because the index is simple, correlates to fatness, and applies to both men and women.
