About this calculator
Calculate rotational mechanical power from torque and speed.
Enter valid values, choose the units you need, then select Calculate. The calculation runs in your browser and does not require an account.
How to use this calculator
What to enter
Enter or select the following as requested: Torque; Speed (rpm); Result unit. Follow the units, valid ranges, examples, and options displayed beside each field.
What the result means
The engineering result is calculated from the dimensions, loads, material properties, flow conditions, or operating values entered. Check the unit system, material assumptions, boundary conditions, safety factor, and whether the model represents static, dynamic, or ideal conditions.
When to use it
Use this for preliminary engineering calculations or to check a worked problem. Verify assumptions and applicable design standards with a qualified engineer before using the result to design, size, or operate load-bearing or safety-critical equipment.
