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.

Kilogram-Force Millimeter [kgf·mm]

Kilogram-force millimeter (kgf·mm) is a unit of torque or moment of force used to quantify small rotational forces where the force is expressed in kilogram-force (kgf) and the distance in millimeters (mm). It represents the torque generated when a force of one kilogram-force is applied at a lever arm length of one millimeter from the pivot point.

This unit is commonly employed in fields such as mechanical engineering, precision instrument calibration, and small machinery design. It is especially useful for measuring or specifying torque in devices requiring fine control over small rotational forces, such as torque on small bolts, delicate mechanical assemblies, or calibration of torque wrenches.

While the standard SI unit for torque is the newton-meter (N·m), kgf·mm provides a convenient scale in applications where the metric system is preferred but the force is expressed in kilogram-force due to historical or practical reasons. For reference, 1 kgf·mm is approximately equal to 9.80665 × 10⁻³ newton-meters.

Using kilogram-force millimeters allows for precise torque measurement in contexts where small-scale torque values are critical to ensure proper assembly and operation of mechanical systems.
