The formula for calculating horsepower from torque and RPM is:

\[Horsepower = \frac{Torque (lb-ft) \times RPM}{5252}\]Where:

- Horsepower: The power output of the engine
- Torque: The rotational force produced by the engine (in pound-feet, lb-ft)
- RPM: The engine speed (in revolutions per minute)
- 5252: A constant derived from the definition of horsepower

- Multiply the torque by the RPM
- Divide the result by 5252

Let's calculate the horsepower for an engine with 200 lb-ft of torque at 5000 RPM:

- Horsepower = (200 × 5000) ÷ 5252
- Horsepower = 1,000,000 ÷ 5252
- Horsepower ≈ 190.4 HP

This visual represents the relationship between torque, RPM, and the resulting horsepower based on our example calculation.
