Engine Torque Calculator


About Engine Torque Calculator (Formula)

The Engine Torque Calculator is a crucial tool used in engineering and automotive contexts to assess the twisting force generated by an engine’s crankshaft. Torque is a fundamental parameter in understanding an engine’s performance, especially in vehicles and machinery. The formula to calculate engine torque is:

Torque (T) = Distance (r) × Force (F)


  • “Distance (r)” is the perpendicular distance from the axis of rotation to the point where the force is applied.
  • “Force (F)” represents the force applied at that distance from the axis of rotation.

In the context of an engine, the formula can be further refined to:

Engine Torque (Te) = Brake Mean Effective Pressure (BMEP) × Engine Displacement / 2


  • “Brake Mean Effective Pressure (BMEP)” is a measure of the engine’s efficiency and combustion pressure.
  • “Engine Displacement” refers to the volume displaced by all the pistons within the engine’s cylinders.

This formula helps calculate the engine’s rotational force, which is crucial for understanding power delivery, acceleration, and overall performance.

The Engine Torque Calculator plays a vital role in designing engines, optimizing power delivery, and assessing mechanical efficiency in various industries, from automotive to industrial machinery. It’s a fundamental tool for engineers and enthusiasts alike to analyze and enhance engine performance.
