What your readers get

The formula and the answer

Each reader sees the formula for the pair and the answer for the number they typed. The steps are on the full page, one link away.

Worked out in the browser

The answer is calculated on the reader’s device. What they type is not sent to a server.

A link back to the full page

The widget links to the full converter, where the sources of each factor are listed.

No sign-up, no ads

The widget needs no account and carries no advertising.

Questions about the embed

Is the embed free to use?

Yes. The widget needs no sign-up and shows no advertising. It keeps a link back to the full converter, so readers can find the steps and the sources.

Does the widget send what my readers type to your server?

No. The answer is calculated in the reader’s browser, and the page makes no network request to compute it. The frame loads the page from converters.tools like any visit; the numbers stay on the reader’s device.

Can I choose other units or a different size?

Choose the units on this page and copy the code again. The width and height are set in the code, so change them there. The widget uses the site’s light theme, and its colors cannot be changed from the code.

The converter is cut off on my page. What do I do?

Raise the height in the code. The preview on this page uses the same height as the code you copy, so check it there first.

My platform does not allow iframes. Can I still link to the converter?

Yes. Use a normal link to the full page of the pair you chose. It works on any platform and leads to the same steps and sources.
