Look closely at the Pi Alignment Theory whitepaper. The formula you've shown above is on page 5. In this formula, the "l" term is a lower-case "L" and not the number "1". This value is used to show the speed of sound in inches per second, or 13548. So multiply your results by 13548 and you'll arrive at the proper and expected answer.
