What is the formula to calculate BMI using weight in pounds and height in inches?

The formula to calculate Body Mass Index (BMI) using weight in pounds and height in inches is indeed to multiply the weight in pounds by 703 and then divide by the height in inches squared. The correct formulation of this process is best represented by the second choice, where you take the weight in pounds, divide it by the height in inches squared, and then multiply by 703, making it clear how the calculation works mathematically.

Using this formula effectively translates the weight and height measurements into a single numerical value that represents a person's body composition relative to their height. This metric is widely used to assess whether an individual has a healthy body weight for a given height.

For clarity, the other options misrepresent the relationship between weight, height, and the scaling factor of 703 necessary for converting the measurement into the BMI framework. Understanding the structure of this formula is crucial for personal trainers as it directly influences their ability to assess and guide clients' health and fitness goals accurately.
