feat(balance): round ~1 pound to 400g, 500g

[scarf005]

Purpose of change

• Descrete volume and weights for items #2505

metricate item weights, part 1.

1. many items weighted around a pound to depict them as 'somewhat heavy'.
2. it could have been weighed 500g or 400g instead.
3. eradicate trace of customary units from the game because SI units are superior in many ways (easy to reason with, used by many, etc)

Describe the solution

replaced all items weighting 450 ~ 500g to 500g, and items weighting 400 ~ 450 to 400g.

Describe alternatives you've considered

making them all 500g to be nice and simple.

Testing

passed automated tests in local environment.

Additional context

~98.4% of existing countries have fully adopted metric system (192/195 countries, with the exception of Liberia, Myanmar, and the United States.)

400 grams to the 500 grams? Just delete this comment if it's not going to be actually useful anymore.

IRL, boxing gloves are standardized by weight. As such, this isn't actually a case of them just slapping a weight of roughly a pound on it, but legitimately what a pair of fairly-standard boxing gloves would weigh.

Not saying it shouldn't be changed, just clarifying that this isn't a case of them just choosing to make them about a pound arbitrarily.

[RobbieNeko]

This seems a little out of place for this PR, given that a Ruger LCR .22 is legitimately about 420 grams IRL (422.4 to be exact). Considering this PR is stated to be primarily about handling cases where something was set to be about a pound for the sake of just making it "somewhat heavy", I'd hesitate to say this really fits. 420 is already a perfectly round number.

[scarf005]

true, tho i was thinking of #2505

[RobbieNeko]

Fair, though I think that nearest 10 grams is already within #2505 's goal. 100% would support rounding the Cobray Streetsweeper to 420g, for example. (And magazines I have no qualms over how you adjust them, those are a lot more variable anyway)

[scarf005]

makes sense. will revert it when i get home.

[RobbieNeko]

460 is actually about the correct weight for 250 ml of sulfuric acid (the calculated weight based on density being 457.5)

[RobbieNeko]

Looks to me like a couple chemicals and firearms got caught in the crossfire when in actuality they've got pretty accurate weights that are still nice rounded numbers regardless

(Also, in hindsight I totally should have just done a single review, but I initially came in only expecting comment on one thing before it turned into 3 haha)

While not in the 500 but rather in the 1500 range, books need some help as well.
