How to convert N·m to lbf·ft
To convert newton-meters to pound-feet, multiply by 0.737562. This is the inverse of the exact factor used to convert pound-feet to newton-meters (1 lbf·ft = 1.3558179483314 N·m), itself derived from the pound-force (4.4482216152605 N) acting over one foot (0.3048 m).
Worked example: automotive wheel nut torque
Many passenger car manufacturers specify wheel nut torque around 110–140 N·m. Entering 120 N·m above returns 88.5 lbf·ft — the figure a US-made torque wrench calibrated in lbf·ft would need to be set to, to apply the same clamping force as the metric spec. Getting this conversion wrong in either direction is a genuine safety issue: under-torquing risks a wheel working loose, over-torquing risks stud or hub damage.
Common mistake: lbf·ft vs lbf·in
Small-fastener torque specs (electronics, instrument panels, small machine screws) are often given in pound-inches (lbf·in) rather than pound-feet, because the values in lbf·ft would be awkwardly small (a fraction of a pound-foot). 1 lbf·ft = 12 lbf·in, so mixing the two up by a factor of 12 is an easy and consequential error — always check which one a spec sheet is actually using before setting a torque wrench or driver. This site's Torque category includes both lbf·ft and lbf·in as separate selectable units specifically to avoid that mix-up.

Frequently asked questions
What is 1 N·m in lbf·ft?
1 newton-meter equals approximately 0.737562 pound-feet.
What's the difference between lbf·ft and lb-ft?
They refer to the same unit — pound-force feet — 'lb-ft' is just informal shorthand for 'lbf·ft'.
Why does torque matter for bolted joints?
Under- or over-tightening a bolted joint changes its clamping force and fatigue life, so torque specs (often given in both N·m and lbf·ft) must be followed precisely, ideally with a calibrated torque wrench.
Does a longer wrench handle change the torque reading?
No — torque is what the wrench measures and applies at the fastener regardless of handle length, but a longer handle lets you apply the same torque with less hand force, which is exactly why breaker bars exist for stuck high-torque fasteners.
