It is trivial to do that with JavaScript as you fill in the content of <output> using Intt, e.g.

    const outputEl = document.getElementById("my-output");
    const currencyFormat = new Intl.NumberFormat("default", {
      style: "currency",
      currency: "ISK",
    });

    outputEl.textContent = currencyFormat.format(value);

Ok, but as a peer comment points out, doing this client-side is fraught / potentially nonsensical to convert a monetary number value to a different currency if you don't know the exchange rate.

Is currency exchange rate even part of the WHATWG standard? You will always need do to do something fraught / potentially nonsensical to convert between different currency, if not on the client, then on the server.
Formatting output values to the user’s locale has nothing to do with currency exchange rate. And JavaScript does the former rather excellently (except when the locale is not supported [ahm, Chromium]).
