So a yard is roughly one meter. It means a kilo-yard is about one kilometer and a centi-yard is one centimeter. How many miles or inches that is, is a conversion problem within the imperial system.
In the same way, a quart is about one liter. Milli-quart is about one milliliters. Easy. How many gills those are is not our problem.
There is no immediate equivalent for weight, although a double-pound would be roughly one kilogram.
Now I’m wondering that if you replace these poster with something like “black babies matter” it would trigger replacement theory before it triggers the pro-life reflex.
My pet theory is that this is because of the assembly line way of thinking of studios. Script -> Casting -> Shooting -> VFX -> Editing -> Profit.
It takes time to develop a good idea and script. If you force a writer to adhere to a strict schedule you’ll get a rush job and bad writing. As long as money keeps flowing in, their assembly line theory is validated.
It’s a mistranslation. The original text said Santa works in eleven dimensions. Time and space mean nothing to that guy. That got turned into Santa working with elves. It’s understandable as the original eldritch texts drive mere mortals readers insane. Multidimensional documentation is the worst.
