How is the modified BMI formula expressed for weight in pounds?

The modified BMI formula for weight in pounds is correctly presented by multiplying the weight in pounds by 703, and then dividing that product by the height in inches squared. This adjustment is necessary because the standard BMI formula, which uses kilograms and meters, results in a different numerical range when using pounds and inches.

In essence, the use of 703 serves to scale the BMI value appropriately so that it aligns with values commonly accepted in health assessments when employing imperial measurements. Therefore, understanding this formula is essential for accurately calculating BMI for individuals whose weight is measured in pounds and height in inches, ensuring that the resulting calculations reflect a person's body mass index accurately.
