LaPotato8 is another one of my favorite Growth/Giantess artists and I feel as though he draws some of the best Growth/Expansion sequences around. Also, I’ll update the gallery every couple of new images (3-5+) rather than after every single image to lessen spam. Anyway, please enjoy the compilation!
EDIT: The artist's old Twitter was banned, and he's personally uploading his works here so I guess I'll put this gallery on the backburner unless that changes. New Link to his Twitter below. I've also included his own gallery go support it.
That would be Mm, mega meters (1,000,000m). Then Gm, giga meters (1,000,000,000m), then Tm, tera meters (1,000,000,000,000m). Nobody really uses anything bigger than Km. I guess because the Earth itself is only 40,000Km in circumference? It would only be useful in an astronomical context, but AU, astronomical units (The distance from the sun to the earth), are used for that instead.
@rubit Yeah, I was on a short internet hiatus but I've updated the link above if you still need it. He seems to be uploading his own gallery here now so I'll probably have to step down. Just search his name here and you should find it.
Here's his gallery link to make it easier to find:
