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.

Ounce-Force Foot [ozf·ft]

Ounce-force foot (ozf·ft) is a unit of torque or moment of force used to measure rotational force in situations requiring finer precision than pound-force foot (lbf·ft) but larger than ounce-force inch (ozf·in). It represents the torque generated when a force of one ounce-force (ozf) is applied at a distance of one foot (ft) from a pivot point. This unit is particularly useful in mechanical engineering, instrumentation, and small-scale mechanical systems where moderate torques are involved.

Ounce-force foot is valuable for quantifying torque in applications such as small machinery, instrument calibration, or assembly of mechanical devices where precise control of rotational force is critical. It helps ensure components are tightened or adjusted correctly without causing damage or failure.

While the newton-meter (N·m) is the SI unit for torque and the pound-force foot (lbf·ft) is common for larger forces, the ounce-force foot unit fits niche applications that require intermediate torque measurements within the imperial system. For reference, 1 ozf·ft equals approximately 0.00885 newton-meters.
