The article is a little unclear whether 1.4×10^17g is the cutoff mass for the definition of a PBH, or the mass above which they calculate a PBH would cause fatal damage.

If it's the latter, that is many orders of magnitude larger than i would have expected!

Yeah, black holes are apparently weak AF. One 9mm round weighs 7*10^1 grams and can ruin my afternoon.

The paper itself has more info. Though I'd be lying if I understood it.

https://arxiv.org/html/2502.09734v1

EDIT: Removed the quote since it wasn't directly relevant. Section II in the paper is probably what you want.

Reminds me of that new series Omni Loop.
