Ounce-Force Inch [ozf·in]

Ounce-force inch (ozf·in) is a unit of torque or moment of force used primarily in industries and applications where very small rotational forces are measured. It represents the torque produced when a force of one ounce-force (ozf) is applied at a distance of one inch (in) from a pivot point. This unit is especially useful in precision engineering, small mechanical assemblies, and electronics, where fine control of torque is necessary.

For example, ounce-force inches are commonly used to specify the torque settings for small screws, delicate instruments, or miniature motors. Since it measures very small torques, ozf·in allows engineers and technicians to ensure components are neither over-tightened nor under-tightened, which could lead to damage or malfunction.

Although the newton-meter (N·m) is the SI unit of torque, and pound-force foot (lbf·ft) is more common in larger mechanical systems, ounce-force inch remains practical in applications requiring detailed precision in the imperial measurement system. To give perspective, 1 ozf·in is approximately 0.007062 N·m.

Kilonewton Meter [kN·m]

Kilonewton meter (kN·m) is a unit of torque or moment of force commonly used in engineering and physics to measure large rotational forces. It represents the torque produced when a force of one kilonewton (kN) is applied at a distance of one meter (m) from a pivot point. Since one kilonewton equals 1,000 newtons, the kilonewton meter is well-suited for applications involving substantial forces and moments.

This unit is widely used in structural engineering, mechanical design, automotive industries, and heavy machinery, where large torques need to be calculated or controlled. For example, in construction, kN·m is used to describe the bending moments in beams, while in automotive engineering, it measures engine torque.

The kilonewton meter aligns with the International System of Units (SI), making it convenient for global standardization and calculations. It simplifies communication of torque values in large-scale applications by scaling up from newton-meters (N·m).

To convert, 1 kN·m equals 1,000 newton-meters. This unit helps engineers ensure safety, performance, and efficiency in designing and operating mechanical systems subjected to significant forces.
