What is the bmi for a 5 foot 3 inch 100 pound girl?

To calculate the Body Mass Index (BMI) for a girl who is 5 feet 3 inches tall and weighs 100 pounds, first convert the height to inches: 5 feet 3 inches is 63 inches. Then, use the BMI formula: BMI = weight (lbs) / (height (inches) x height (inches)) x 703. Plugging in the values, BMI = 100 / (63 x 63) x 703, which equals approximately 17.7. This BMI indicates that she is underweight according to standard classifications.
