Gram-Force Millimeter [gf·mm]

Gram-force millimeter (gf·mm) is a unit of torque or moment of force used to measure very small rotational forces, typically in delicate mechanical systems or precision instruments. It represents the torque produced when a force of one gram-force (gf) is applied at a distance of one millimeter (mm) from a pivot point.

This unit is particularly useful in fields such as microengineering, watchmaking, electronics, and small-scale mechanical testing, where tiny torques need to be accurately measured and controlled. For example, gf·mm is often used to specify the torque for miniature screws or the resistance of small mechanical components.

Although the newton-meter (N·m) is the standard SI unit for torque, gf·mm offers a practical scale for extremely low torque measurements, providing precision that is more intuitive when dealing with tiny forces and distances. To convert, 1 gf·mm is approximately 9.80665 × 10⁻⁶ N·m.

Using gram-force millimeters allows engineers and technicians to ensure proper functioning of small devices by preventing over-tightening or insufficient torque application.

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.
