BMI Calculator
- BMI Chart
The BMI calculator is used to approximate a
healthy body weight relative to an individual's height.
Many interpret the BMI values to
approximate the percentage of body fat; however that is not the
intention of the body mass index. Several
methods can accurately measure body fat, such as
hydrodensitometry (submersion in water), and calipers that
measure skin fold thickness.
To calculate your BMI, enter your height
and weight in the BMI calculator. Then you can
use that calculation to approximate your relative condition
using the BMI chart below.
We then discuss the various BMI categories
for your own BMI calculation.

BMI <

"Underweight" -- If you are a competitive
athlete, or have family members of similar genetic qualities -
and maintain a healthy lifestyle - this BMI / body mass
index range would be appropriate. However, dieting to
arrive at this range could put you at risk of malnutrition, and
offers no additional health benefits.

BMI 18.5 -
24.9
"Normal Weight" -- In this BMI /
body mass index range, you are in the healthy range
for adults. You are at the lowest level of risk for
hypertension, heart disease and diabetes.

BMI 25.0 -
29.9
"Overweight / Pre-Obese" -- If you fall
into this BMI / body mass index range, you
have a slightly elevated chance for hypertension, heart disease
and diabetes. A moderate level of exercise and attentiveness to
healthy eating can easily reduce your weight and associated
health risks.

BMI >
30.0
"Very Overweight / Obese" -- In this
BMI / body mass index range, you have a
significantly elevated risk for hypertension, heart disease and
diabetes. Through exercise and healthy eating, a 10% reduction
in weight can materially diminish the risk for these
conditions.

Important BMI
Notes
The BMI calculator can overestimate
body fat in athletes or individuals with muscular builds.
The BMI calculator can underestimate
body fat in older adults who may have lost muscle mass with
aging.
The BMI calculator and BMI
chart is not intended to diagnose your medical
condition. If you have any questions or concerns, please see
your doctor.
