The BMI Chart by age is a pretty useful tool in the health world. It's a measurement of your Body Mass Index for women and men. It can help determine if you're at a healthy weight for your height. The chart was developed by Adolphe Quetelet in 1830 and it showed that most people have an average body weight with only 5-10% being below or above what would be considered normal.
BMI is calculated from the person's weight in kilograms divided by their height in meters squared (kg/m2). One might say that this equation works because it takes into account both the volume and density of human tissue. This BMI calculator will give you an estimate, but the best way is to talk with a doctor or dietitian.
The Body Mass Index calculation is based on health research and study of population.
