Frequently Asked Questions
-
What is a dyne millimeter used for?
-
It is used to describe very small torques in precision instruments, like watch movements and small gear trains, as well as for low-range torque outputs in small motors and laboratory measurements.
-
What does one pound-force inch represent?
-
One pound-force inch is the torque produced by a one pound-force applied perpendicular to a lever arm one inch long. It is commonly used in imperial engineering to quantify turning forces.
-
Why is this conversion important?
-
It helps express very small torques originally measured in cgs units as pound-force inches, which are more commonly used in engineering practices involving small fasteners and motors.
Key Terminology
-
Dyne millimeter [dyn*mm]
-
A cgs-derived torque unit, representing one dyne of force applied at a one millimeter lever arm, equaling 1×10⁻⁸ newton-metres.
-
Pound-force inch [lbf*in]
-
An imperial unit of torque representing the moment produced by one pound-force applied at a one inch lever arm.
-
Torque
-
A measure of the rotational force or moment produced by a force acting at a distance from an axis.
