Newton-Meters to Foot-Pounds (Nm to ft-lbs)
1 N·m = 0.737562 lbf·ft
To convert newton-meters to foot-pounds: foot-pounds = newton-meters × 0.737562
| newton-meters | foot-pounds |
|---|---|
| 5 N·m | 3.688 lbf·ft |
| 10 N·m | 7.376 lbf·ft |
| 20 N·m | 14.75 lbf·ft |
| 25 N·m | 18.44 lbf·ft |
| 35 N·m | 25.81 lbf·ft |
| 40 N·m | 29.5 lbf·ft |
| 50 N·m | 36.88 lbf·ft |
| 100 N·m | 73.76 lbf·ft |
| 120 N·m | 88.51 lbf·ft |
| 200 N·m | 147.5 lbf·ft |
In inch-pounds: 1 N·m = 8.85075 in-lbs, so 5 Nm = 44.25 in-lbs and 10 Nm = 88.51 in-lbs.
One newton-meter is 0.737562 foot-pounds (pound-force feet). The factor comes from the exact definitions in NIST SP 811: 1 lbf = 4.4482216152605 N and 1 ft = 0.3048 m, so 1 lbf·ft = 1.3558179 N·m and 1 N·m = 1 ÷ 1.3558179 = 0.737562 lbf·ft.
Formula
foot-pounds = newton-meters × 0.737562
Example: 8 newton-meters = 5.9005 foot-pounds.

Good to know
Quick estimate: multiply by 3 and divide by 4. 100 Nm × 3 ÷ 4 = 75 ft-lbs (the exact answer is 73.76), close enough to sanity-check a spec but not to set a torque wrench — use the exact figure from the converter for that.
Workshop manuals from European and Asian makers usually print torque in N·m, while US manuals and many torque wrenches read in ft-lbs. Small fasteners are often specified in N·m values under 25, which is less than 20 ft-lbs — below the bottom of many 1/2-inch drive wrenches. For those, convert to inch-pounds instead (1 N·m = 8.85075 lbf·in) and use a 1/4-inch or 3/8-inch drive inch-pound wrench.
"Foot-pounds", "ft-lbs", "lb-ft" and "lbf·ft" all mean the same unit of torque here. Engineers prefer lb-ft for torque to keep ft-lb for work (energy), but the number is identical. Always tighten to the figure in your own vehicle or product manual; this page only changes the units.
Engine spec sheets: a car listed at 400 N·m of torque makes 295 lb-ft. Our torque converter also handles kgf·m, N·cm and oz-in and turns torque and rpm into horsepower.
Frequently asked questions
How do you convert Nm to ft-lbs?
Multiply newton-meters by 0.737562. For example, 50 Nm × 0.737562 = 36.88 ft-lbs.
How many ft-lbs is 100 Nm?
100 Nm is 73.76 ft-lbs.
How many ft-lbs is 25 Nm?
25 Nm is 18.44 ft-lbs (221.3 in-lbs).
How many ft-lbs is 10 Nm?
10 Nm is 7.38 ft-lbs, or 88.5 in-lbs.
How many ft-lbs is 40 Nm?
40 Nm is 29.50 ft-lbs.
Is Nm bigger than ft-lbs?
No. One foot-pound is 1.3558 Nm, so a foot-pound is about 36% larger than a newton-meter. The ft-lb number is always the smaller of the two.
What is Nm in inch-pounds?
1 N·m = 8.85075 in-lbs. Multiply by 8.85 for small fasteners specified in N·m.
