Newton Centimeter [N·cm]


Newton centimeter (N·cm) is a unit of torque that measures the rotational force applied when a force of one newton is exerted perpendicularly at a distance of one centimeter from the axis of rotation. It is particularly useful for small-scale or precision applications where forces are relatively low and distances are short, such as in electronics, robotics, watchmaking, and laboratory experiments. A higher N·cm value indicates stronger torque and greater resistance to rotational motion, while a lower value signifies less force and easier rotation. Engineers and designers use this unit to calculate torque, angular acceleration, and energy requirements for small mechanical components like gears, motors, and sensors. By combining force and a short rotational distance, newton centimeter provides a practical and precise measure for analyzing and managing torque in compact or delicate systems, ensuring accuracy, efficiency, and stability in micro-scale mechanical and engineering 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.
