Hp to Torque Calculator

1. What is a Hp to Torque Calculator?

Definition: This calculator converts horsepower and speed into torque, measuring rotational force.

Purpose: It assesses the torque output of engines or motors for engineering and industrial applications.

2. How Does the Calculator Work?

Torque is calculated using:

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

Speed conversions:

  • RPM: Direct use
  • rad/s: RPM = (rad/s × 60) / (2π)
  • Hz: RPM = Hz × 60
Horsepower conversions:
  • hp(I): Direct use
  • hp(M): hp(I) = hp(M) × 0.98632
  • hp(E): hp(I) = hp(E) × 0.99933
  • ahp ≈ hp(I)
  • hp(S): hp(I) = hp(S) × 13.1548
Torque conversions:
  • N·m = lb·ft / 0.737562
  • kN·m = lb·ft / 737.562

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

3. Importance of Torque Calculation

Details: Torque determines rotational force, essential for understanding motor performance and mechanical design.

4. Using the Calculator

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