Frequently asked questions
What does Power Converter do?
Watts, kilowatts, horsepower, BTU/hr and more. The whole thing runs in your browser tab, so it is ready the moment the page finishes loading.
Is Power Converter free to use?
Yes. Power Converter is completely free on ToolMunch — no trial, no premium tier holding back the main feature, and no daily or hourly cap on how many times you can use it.
Do I need to create an account or sign up?
No. There is no account, no email address, and no login. Open Power Converter, do the job, and take the result — nothing is gated behind a signup form.
Are the numbers I enter sent to a server?
No. Power Converter runs entirely inside your browser tab, so what you type never leaves your own device. Nothing is uploaded, which means there is no copy of it on a server to worry about.
Does Power Converter work on Mac, Windows, and phones?
Yes. Power Converter runs in any modern web browser on Windows, macOS, Linux, Chromebook, Android, and iOS. There is nothing to download or install.
Can I use it as many times as I want?
Yes. There is no queue, no per-hour quota, and no counter that runs out — run Power Converter as often as the work needs.
