Understanding the different parameters
Torque (lb-ft)
Torque is a measure of rotational force, often described as the "twisting power" of an engine. It represents the engine's ability to do work and is measured in pound-feet (lb-ft) in this calculator. Higher torque values indicate an engine's capacity to move heavier loads or accelerate a vehicle more quickly.
RPM (Revolutions Per Minute)
RPM, or revolutions per minute, refers to how many times the engine's crankshaft completes a full rotation in one minute. It is a measure of engine speed. Different RPM levels can significantly impact an engine's performance characteristics, with higher RPMs often providing more power output depending on the engine's design.
How to calculate horsepower
Horsepower is calculated using the relationship between torque and engine speed (RPM).
By multiplying torque by RPM and dividing by 5252, you can calculate the engine's horsepower. This formula helps engineers, mechanics, and enthusiasts understand an engine’s performance and its ability to generate power under specific conditions.
