How much (weight in kilograms) dried whole black pepper would fit into 1 cubic meter at 12% maximum moisture?

1This may not be the correct site for this question--this sounds like mathematics.– mechCommented Feb 8, 2018 at 19:49

3@mech "What is the density of pepper?" (which is basically the underlying question) wouldn't be on topic on a math-ish site. I think this is okay enough here. If it's off-topic it'd probably be because it's commercial/industrial scale, so it's maybe not exactly cooking, but eh, if we'd answer it if it asked about 1L instead of 1m^3, I'm inclined not to split hairs.– Cascabel ♦Commented Feb 8, 2018 at 20:48

Good point, and fair enough.– mechCommented Feb 8, 2018 at 20:49

It does sound like a homework question, though :)– EricaCommented Apr 16, 2019 at 0:13

USDA nutrition facts say it's 2.9 grams per teaspoon, which gives 588kg/m^3.

1no, that site is not accurate .. the non ground pepper (whole pepper) take much space than ground pepper because it's round. So, ground pepper may weigh that much, but dry whole pepper is clearly will not fit that much of weight of dry whole pepper. Commented Feb 9, 2018 at 6:33

2@Pretty_Girl100 I also went and measured myself. I have a 14.1oz container of whole black pepper, and it's 700mL. That gives 2.8g/tsp, close enough to the USDA's number, so I am inclined to trust that it's approximately correct. (I also trust the USDA's actual measurements more than speculation. It's a government agency that uses multiple independent reports to compile that data. As for the ground vs whole things, it may well be less dense when ground because it ends up very irregular and packs badly.)– Cascabel ♦Commented Feb 9, 2018 at 6:40

1Further evidence for ground being less dense being correct (beyond the USDA being a trustworthy source): the brand that sells the whole pepper I have also sells ground, same container size, and it's 12.7 oz for their coarse ground and 12.3 oz for fine.– Cascabel ♦Commented Feb 9, 2018 at 14:47

1@Pretty_Girl100 Worst case, since unground peppercorns are pretty spherical, assume a packing fraction of 0.75. But ground pepper is light enough that it will retain a significant amount of air in the mix so it's not at all unreasonable for it to end up being roughly the same weight as unground unless effort is expended on compressing it.– PerkinsCommented Apr 15, 2019 at 23:26
