Worked examples
Converting 5 newton-meters
Multiply 5 by 8.8507458. That gives 44.2537 pound-inches. A quick sanity check: one newton-meter is larger than one pound-inch, so the number should get bigger — and it does.
Converting 72 newton-meters
72 × 8.8507458 = 637.2537 pound-inches. Working backwards, 637.2537 ÷ 8.8507458 returns 72 newton-meters, which confirms the factor is applied the right way round.
