Hehe, that's awesome, so glad to hear that! Mathjs is really great with units out of the box, and they also have a custom unit feature that I may use in the future to beef up the unit library.

And nice find on that setting, I have a handful of other settings I want to implement too: https://github.com/jaredreich/calcutext/issues/2

Thank you for trying it out, it means a lot to me.
