Using the IBW formula for a male who is 66 inches tall, what is the IBW in pounds?

Explanation:
The estimate uses a simple, fixed-per-inch approach: for men, start with 106 lb for the first 5 feet, then add 6 lb for every inch above 5 feet. At 66 inches, that’s 6 inches over 5 feet. So the calculation is 106 + (6 × 6) = 106 + 36 = 142 pounds. This matches the given result. Note that some other IBW formulas (like Devine) give a similar value for this height, typically a little lower (around 140–141 lb), but the commonly used straightforward method yields 142 lb.
