Formula and methodology
Formula: Power = torque x 2pi x RPM/60; mechanical horsepower = watts/745.699872.
The calculator converts measured torque and speed; it does not infer engine performance from a vehicle or gear ratio.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Torque — N m; minimum 0; maximum 100000000
- Rotational speed — RPM; minimum 0; maximum 10000000
Worked example
| Input | Value |
|---|---|
| Torque | 200 |
| Rotational speed | 3000 |
200 N m at 3,000 RPM produces about 62.8 kW or 84.2 mechanical hp.
Assumptions and limits
- Torque is in newton-metres and horsepower means mechanical horsepower.
- Losses, drivetrain efficiency, and transient behavior are excluded.
