Every unit of a family, together. Choose a family to start from its example; type in any field and the rest follow, and the line above with them. The ring beside a unit makes it the answer.

The link holds the line after the # sign, a part browsers never send to a server, with its meaning and its answer spelt out, so it opens the same conversion anywhere. Copy link also puts it in the address bar, so it stays in this browser’s history.

Nothing is sent and nothing is stored. Every number is worked out in your browser, and the page makes no request after it has loaded. On zeromile.tools it is served with connect-src 'none', so the browser itself refuses any connection its script might try to open.
