Thanks for the reminder =)

Alas, I often have to do these kinds of calculations on a random publicish computer or my phone and Google's converter is platform-independent. But not using Google services when feasible is certainly net good.

And of course my TI-89 had equally good unit conversion for practical purposes (since you can define your own units) so somehow the world is still playing catchup to a calculator from the 90s...

If you’re organized enough to have space for Termux on your phone, it does wonders in this department. I feel silly every time I punch Python code into that teensy touch keyboard, but damned if I know anything else that has a better input UI and isn’t orders of magnitude less versatile. (Maple Calculator and microMathematics are still on the “there was an attempt” level, in my experience.)

There's an Android GUI for a units(1) calculator in F-Droid. I have it on my phone.

The TI-89 was/is an amazing device.
