Torque Formulas and Conversions

Torque Explained In the simplest sense Torque = Force * Length

Torque is derived and traceable to SI units of length,  mass,  and time.

The meter is the length of the path traveled by light in vacuum during a time interval of 1/299 792 458 of a second.

The kilogram is the unit of mass; it is equal to the mass of the international prototype of the kilogram.

The second is the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyper-fine levels of the ground state of the cesium 133 atom. — Torque , also called  moment  or  moment of force  is the tendency of a force to rotate an object about an axis, fulcrum, or pivot. Just as a force is a push or a pull, a torque can be thought of as a twist.

To convert from one unit of torque to another, requires knowing the appropriate conversions.

Torque =  Force  x Length

Examples

Force  1N = 0.2248089431 lbf         Length 1m = 3.280839895 ft

—1 N-m = 0.2248089431 x 3.280839895 = 0 .7375621489  ft-lbf

Force  1N = 0.2248089431 lbf         Length 1m = 39.3700787    in

—1 N-m = 0.2248089431 x   39.3700787=  8.50745782  in-lbf

Everything we do, we believe in changing how people think about force and torque calibration.  Morehouse believes in thinking differently about force and torque calibration and equipment.  We challenge the "just calibrate it" mentality by educating our customers on what matters, what causes significant errors, and focus on reducing them.  Morehouse makes our products simple to use and user-friendly.  And we happen to make great force equipment and provide unparalleled calibration services.
