Frequently asked questions

How is this different from torque power?

For rotating shafts use P = torque x angular speed instead; both describe the same quantity.

What is one horsepower in watts?

One mechanical horsepower equals about 745.7 watts.

What do I need to enter into the Mechanical Power Calculator?

Just 2 values: force, velocity. Every field starts with a realistic example, so you can change one number at a time and watch the result update instantly.

How does the Mechanical Power Calculator work out the answer?

Power P = W/t = F x v, measured in watts. It applies the formula P = F v and shows the working so you can check each step by hand.

Is the Mechanical Power Calculator free, and do I need an account?

It is completely free with no sign-up, no download and no usage limit. Everything is calculated in your browser, so the numbers you type never leave your device.
