Pound-feet to newton-meters
Type a value in lb·ft to get it in N·m instantly.
That's 1.23× as much torque as a car wheel nut, while a family car engine is 1.84× more. On a 30 cm wrench, that is a pull of about 46.08 kg.

How much turn is that?
Reference torques are typical values. Always use the figure in your own service manual for wheel nuts and engine bolts.
The math
How to convert lb·ft to N·m
To convert pound-feet to newton-meters, multiply by 1.35582.
Example: 100 lb·ft × 1.35582 = 135.582 N·m.
In the other direction, 1 N·m = 0.737562 lb·ft.

The units
About these units
Pound-feet (lb·ft)
A pound-foot is one pound of force at one foot from the pivot, about 1.356 N·m. US wheel nuts are usually quoted in it.
Newton-meters (N·m)
The newton-meter is the SI unit of torque: one newton pushing at one meter from the pivot. Car specifications worldwide quote it.
