Well, there aren’t any real scientific definitions but there sure are legal and regulatory definitions.
(I haven’t checked the local requirements but there’s micro voltage, low voltage and high voltage. Micro voltage is basically anything below 12v - for anything above that you need to be a certified electrician. Doubly so if you go above household voltages)
Who’s defining low and high here?
Magnetar looking at every voltage that’s ever occurred on Earth: Aw, that’s cute.
One of the scienc-y YouTubers said, IIRC, around 400V.

For AC the definitions are
For DC
Above are from the Blue Book
Neat, I didn’t realize they were defined like this but that totally makes sense for regulations and such. Thanks!
What’s ELV? There’s not a single mention of it in that pdf.
Edit: nevermind, I found it on wikipedia. Extra-low
Sorry ELV is in a blue book supplement not in the main book. Extra low voltage work in Australia doesn’t need a license, just have to be competent.
Not the one I was thinking of but it does define Extra low voltage
