Torque, RPM and Power Calculator

Calculates the relationship between torque (Nm), rotational speed (RPM), and power (Horsepower - HP / Kilowatt - kW) of motors. Enter two values to find the third.

Source / method note

Calculations are based on fundamental physical formulas in engineering standards (Power = Torque × Angular Velocity). Ideal conditions are assumed (efficiency losses are not included).

Legal / official rate note

This tool is for educational and general information purposes. Certified engineering calculations are required for industrial projects and critical system designs.
