RPM to Torque Calculator:
Enter the values of horse power and speed, S to generate the value of Torque, T(ft.lb).
RPM to Torque Formula:
The RPM to torque conversion quantifies the rotational force an engine produces at a specific speed.
Torque, T(ft.lb) in pound feet is equated by dividing the product of 5252.08 and power in horse power, P by speed, S in rpm.
RPM to Torque,T(ft.lb) = (5252.08 * P) / S
T(ft.lb) = Torque in pound feet, ft.lb
P = Horse power.
S = Speed in rpm.
RPM to Torque Calculation:
1. A sports car’s engine produces a power of 300 horsepower at 6000 RPM. Calculate the torque output at this engine speed.
Given: Power (P) = 300 HP, Speed (S) = 6000 RPM.
Torque, T(ft.lb) = (5252.08 * P) / S
T(ft.lb) = (5252.08 * 300) / 6000
T(ft.lb) = 262.604
2. The generated torque in economy car’s engine is 157.56 ft.lb at 4000 RPM. Determine the horse power generated at this speed.
Given: T(ft.lb) = 157.56 ft.lb, Speed (S) = 4000 RPM.
Torque, T(ft.lb) = (5252.08 * P) / S
157.56 = (5252.08 * P) / 4000
P =120HP.
