Torque to Hp Calculator

Power (W): Power (kW): Mechanical Horsepower (hp(I)): Metric Horsepower (hp(M)): Electric Horsepower (hp(E)): Air Horsepower (ahp): Boiler Horsepower (hp(S)):

1. What is a Torque to Hp Calculator?

Definition: This calculator converts torque and speed into power and various horsepower units.

Purpose: It evaluates engine or motor performance across different power standards for engineering and industrial use.

2. How Does the Calculator Work?

Mechanical horsepower is calculated using:

\[ \text{hp(I)} = \frac{\text{Torque (lb·ft)} \times \text{RPM}}{5252} \]

Speed conversions:

RPM: Direct use
rad/s: RPM = (rad/s × 60) / (2π)
Hz: RPM = Hz × 60

Power and other horsepower units:

Power (W) = hp(I) × 745.7
kW = W / 1000
hp(M) = W / 735.49875
hp(E) = W / 746
ahp ≈ hp(I)
hp(S) = W / 9812.5

Explanation: Torque is converted to lb·ft, speed to RPM, then hp(I) is computed and converted to other units.

3. Importance of Power Calculation

Details: Different horsepower units suit specific contexts (e.g., hp(I) for engines, hp(S) for boilers), ensuring accurate performance assessment.

4. Using the Calculator

Tips: Enter torque (N·m, lb·ft, kN·m) and speed (RPM, rad/s, Hz; >0). Results include W, kW, hp(I), hp(M), hp(E), ahp, and hp(S).
