How do you convert Newton-meters to pound-feet?

To convert Newton-meters (N·m) to pound-force feet (lbf·ft), multiply the N·m value by approximately 0.73756. Conversely, multiply the lbf·ft value by 1.35582 to get N·m.

Torque is the rotational equivalent of linear force. It measures the force that causes an object to rotate about an axis, calculated as the force multiplied by the perpendicular distance from the axis (lever arm).

What units are standard in automotive engine torque specifications?

Engine torque specifications are typically expressed in Newton-meters (N·m) in metric-based countries, and in pound-force feet (lbf·ft or foot-pounds) in the United States and United Kingdom.

What is Torque? Rotational Mechanics Explained

In classical physics, torque is the rotational counterpart of linear force. Just as a force pushes or pulls an object to change its linear velocity, a torque twist or pivots an object about an axis to change its angular velocity. The SI unit for torque is the **Newton-meter (N·m)**, which represents the force of one Newton applied perpendicularly to a lever arm of one meter.

Automobile mechanics, aerospace designers, and engineers use torque conversions regularly to calibrate tools, engines, and mechanical fasteners.

Torque Units Comparison

Different engineering disciplines specify torque parameters using standard scales:

Newton-meter (N·m): The metric standard. Widely used in motor diagnostics and international engineering calculations.
Pound-force foot (lbf·ft): Often called foot-pounds. The imperial unit standard in US automotive specifications.
Pound-force inch (lbf·in): Used in precision applications (e.g. bicycle components, electric motors, and computer hard drive casings).
Kilogram-force meter (kgf·m): An older metric unit based on gravitational force.
