Frequently Asked Questions
-
What is a newton millimeter used for?
-
It is used to express small torque values in precision engineering, such as tightening screws in electronics or calibrating micro-motors.
-
Why convert newton millimeters to kilogram-force millimeters?
-
To translate torque measurements between SI units and gravitational units, ensuring compatibility with legacy equipment and documentation.
-
Does local gravity affect the conversion accuracy?
-
Yes, the conversion assumes standard gravity; deviations in local gravitational acceleration can cause minor inaccuracies.
Key Terminology
-
Newton millimeter [N·mm]
-
A torque unit representing the moment from a force of one newton applied perpendicularly at a lever arm of one millimeter.
-
Kilogram-force millimeter [kgf·mm]
-
A torque measurement equal to the moment from a force of one kilogram-force applied over one millimeter; kilogram-force is based on standard gravity.
-
Torque
-
A measure of rotational force, often expressed as force multiplied by distance from a rotation axis.
