Just remembered this plug-in: https://forum.audacityteam.org/t/quick-conversion-calculator/15589/2
It’s a “Quick conversion calculator” that is available from the Audacity Generate menu.
Although it does not actually “generate” anything, I made it as a Generate type plug-in so that it does not require an audio selection, though if there is no audio selection when the plug-in is run, a new audio track will be created as a by-product.
