Newton Meter [N·m]

Newton meter (N·m) is the standard SI unit of torque, measuring the rotational force applied to an object around an axis. It combines force in newtons (N) with distance in meters (m) from the axis of rotation. One newton meter represents the torque generated when a force of one newton is applied perpendicularly at a distance of one meter from the rotation axis. This unit is widely used in physics, mechanical engineering, automotive design, robotics, and industrial applications to quantify torque, rotational performance, and mechanical efficiency. A higher N·m value indicates stronger torque and greater ability to cause angular acceleration, while a lower value signifies less rotational force. Engineers and designers use this measure to calculate torque requirements, optimize machinery, ensure component stability, and prevent mechanical failure. By linking force and rotational distance, newton meter provides a practical, precise, and universally recognized standard for analyzing and managing torque in a variety of mechanical, industrial, and scientific applications.

Pound-Force Foot [lbf·ft]

Pound-force foot (lbf·ft) is a unit of torque or moment of force commonly used in the United States and other countries that employ the imperial system. It measures the rotational force applied at a distance of one foot from a pivot point. Specifically, it represents the torque produced when a force of one pound-force (lbf) is applied perpendicular to a lever arm that is one foot (ft) long.

This unit is widely used in mechanical engineering, automotive industries, and machinery design to quantify twisting forces that cause rotation. For example, when tightening bolts, the torque applied is often specified in lbf·ft to ensure proper fastening without over-tightening. Similarly, engine torque ratings are frequently expressed in pound-force feet, indicating the rotational force an engine can generate.

While the SI unit of torque is the newton-meter (N·m), lbf·ft remains popular in practical applications within the imperial system due to familiarity and ease of use. To convert, 1 lbf·ft equals approximately 1.356 N·m.
