Torque Converter

Convert between newton-metres, pound-feet, and kilogram-force metres, the units used to rate engine and motor output.

Torque Explained Through the Engine Spec Sheets People Actually See It On

Torque is the same physical quantity as moment of force, rotational force applied around a pivot, but the term “torque” specifically gets used in everyday and automotive contexts, most visibly on engine and motor specification sheets alongside horsepower, where the two figures actually describe genuinely different aspects of an engine’s performance. Torque describes the raw rotational twisting force an engine produces at a given moment, which is why a high-torque engine feels powerful pulling away from a standstill or hauling a heavy load at low speed, while horsepower, being torque multiplied by rotational speed, describes the rate at which that twisting force can do work over time, which is why a high-horsepower engine tends to excel at sustained high-speed performance rather than low-speed pulling power. This distinction is exactly why two vehicles can advertise similar horsepower figures while feeling genuinely different to drive, since one might achieve that horsepower through high torque at relatively low engine speed, while the other achieves the same horsepower figure through lower torque spun at much higher engine speed, a difference torque and horsepower together describe far more completely than either figure could alone. Converting torque units follows the identical force-times-distance logic already covered under moment of force, since the two terms describe the same underlying physical quantity under different names.
