FAQ

Frequently Asked Questions

How do I convert lb-ft to Nm?
Multiply pound-feet by 1.35582. For example, 80 lb·ft × 1.35582 ≈ 108.5 N·m.
How many Nm is 100 lb-ft?
100 × 1.35582 = 135.6 N·m. As a rough mental check, multiply pound-feet by 1.35 — that gets you within half a percent.
My torque wrench reads lb-ft but the manual says Nm — what do I do?
Convert the manual's figure before you set the wrench: divide N·m by 1.35582 to get lb·ft. Getting this backwards applies about 84% too much or too little torque, which is enough to shear a bolt or leave a joint loose.
How do I convert lb-ft to lb-in?
Multiply by 12, since a foot is 12 inches. So 5 lb·ft = 60 lb·in. Small fasteners and electronics are usually specified in lb·in or even ounce-inches.
