Our HP to RPM calculator makes it easy to calculate RPM from horsepower. Input horsepower and torque to get accurate RPM results.
Understanding the relationship between horsepower (HP) and revolutions per minute (RPM) is essential for engineers, mechanics, and enthusiasts alike. Our HP to RPM Calculator has been designed to make this calculation effortless, allowing you to derive RPM based on horsepower and torque values in just a few seconds. Whether you're working on an automotive project or analyzing machine performance, this tool is here to save you time and ensure accuracy.
Horsepower is a unit of power that measures the rate at which work is done. In mechanical systems, RPM (revolutions per minute) refers to the number of complete rotations a component, such as an engine shaft, makes in one minute. A simple formula defines the relationship between HP, RPM, and torque:
HP = (Torque × RPM) / 5252
From this, you can rearrange the formula to calculate RPM:
RPM = (HP × 5252) / Torque
This equation forms the backbone of our HP to RPM Calculator, providing precise results based on your input values. If you are interested in calculating torque from RPM and HP, you can also try our HP to Torque Calculator.
Our calculator is designed with simplicity in mind. Follow these steps to use it effectively:
By integrating unit conversion into the process, the tool ensures compatibility with different measurement systems, making it versatile and user-friendly.

Let's consider an example to demonstrate the calculation:
Scenario: You have an engine with 100 HP and 300 lb-ft torque. What is the RPM?
Using the formula:
RPM = (HP × 5252) / Torque
Substitute the values:
RPM = (100 × 5252) / 300 = 1750 RPM
This calculation shows that the engine operates at 1750 RPM when delivering 100 HP and 300 lb-ft of torque.
To provide quick insights, here's a handy chart that outlines common horsepower and torque combinations and their corresponding RPM values:
| Horsepower (HP) | Torque (lb⋅ft) | RPM |
|---|---|---|
| 50 | 200 | 1313 |
| 75 | 250 | 1576 |
| 100 | 300 | 1750 |
| 150 | 350 | 2251 |
| 200 | 400 | 2626 |
