To calculate Body Mass Index (BMI), divide the patient's weight in pounds by their height in inches squared, then multiply the results by a conversion factor of 703. For someone who is 5 feet 5 inches tall (65 inches) and weighs 150 pounds, the calculation would look like this: [150 ÷ (65)2] x 703 = 24.96.
In this example, 24.96 is what would be entered into the Wellness Score.
