Worked examples
Converting 5 pound-feet
Multiply 5 by 1.3558179. That gives 6.7791 newton-meters. A quick sanity check: one pound-foot is larger than one newton-meter, so the number should get bigger — and it does.
Converting 72 pound-feet
72 × 1.3558179 = 97.6189 newton-meters. Working backwards, 97.6189 ÷ 1.3558179 returns 72 pound-feet, which confirms the factor is applied the right way round.
