Show HN: I made a web-based notepad with a built in unit calculator

Nice - I'll give it props for:

> 1 metre + 8 chain = 161.9344 m

> 1 tonne + 1 short ton = 1.90718474 t

> 1 tonne + 1 long ton = 2.0160469 t

and give it a pass for not supporting pre 1963 UK | US historic weights and measures .. that's getting into a pretty specific use case where Standards nerds like to have a clear display of what conversion factors are in play and what provenance those factors have.

Time Zone support (on your About ToDo) will be interesting, historic computations with daytime savings support will be a quagmnire :-)

The SHARE DOC URLs seem a bit long - something like "base64 full text of doc as an URL" I guess.

Will this hit a URL length limit if widespread use becomes a thing?

do server side storage and doc hash .. which has issues of its own.

I'm (slowly) working on something that can eat up PSD2 data from banks and parse it into some usable data, but I'm bad at nicely presenting stuff. It would be great to see your tool and get some inspiration, or maybe even use it.

Very cool!

This reminds me of the open source NoteCalc: https://bbodi.github.io/notecalc3/

It was discussed on HN, you might look there for inspiration: https://news.ycombinator.com/item?id=25495393

This is great! Love Soulver too, but having it in the browser is fantastic. Well done!

I hadn't seen that before, it's very impressive!
