110 grams per cup is simply what the arithmetic says black pepper weighs at that volume — real kitchens work in teaspoons or a handful of cranks from a mill, since its sharp heat announces itself in even a small dose.
Black, white, and green peppercorns all come from the exact same plant, Piper nigrum, harvested and processed at different stages — black pepper is picked unripe and dried whole with the skin on, white pepper has the outer skin removed after a soaking process (giving a milder, less complex heat), and green pepper is picked even earlier and preserved (often brined or freeze-dried) before full drying — pink peppercorns, by contrast, come from an entirely different, unrelated plant despite the shared "peppercorn" name.
Freshly ground black pepper carries noticeably more aroma and a sharper bite than pre-ground pepper that's been sitting in a shaker for months, since pepper's flavor and heat come substantially from volatile compounds that dissipate once the peppercorn is cracked open — this is the real, practical reason so many kitchens and recipes favor a pepper mill over pre-ground pepper, beyond just tradition or texture preference.
Freshly ground black pepper loses volatile aromatic compounds relatively quickly compared to whole peppercorns, which is why pre-ground pepper (used for this site's 106g-per-cup figure) tastes noticeably flatter than pepper ground fresh at the table — a real, tasteable difference that has nothing to do with the conversion math itself.
Pepper mills exist because pre-ground pepper loses its aromatic punch fast — cracking or grinding a peppercorn ruptures the same tiny oil sacs responsible for its heat and fragrance, and once those oils are exposed to air they start dissipating within weeks rather than the years a whole, unbroken peppercorn can hold onto them.

Frequently asked questions
Are black, white, and green peppercorns different plants?
No — they all come from the same plant, Piper nigrum, just harvested and processed at different stages of ripeness, which is what produces their different colors and flavor intensities; pink peppercorns, however, genuinely come from a different, unrelated plant.
Why does freshly ground pepper taste stronger than pre-ground pepper?
Much of pepper's punch lives in aromatic compounds sealed inside the peppercorn until it's cracked, and those compounds start fading the moment they're exposed to air — a jar of pre-ground pepper that's been open a while has already lost a fair amount of that punch compared to pepper cracked fresh right before it goes on the food.
Why is white pepper milder than black pepper if they're the same plant?
White pepper has its outer skin removed through a soaking process before drying, and that skin carries some of the sharper, more complex flavor compounds — removing it produces a milder, more subtly earthy heat than black pepper's fuller flavor.
Does ground pepper lose potency over time the way ground cinnamon does?
Yes, similarly — this site lists a 2-3 year window for best potency, ground or whole (whole peppercorns hold their flavor a bit longer than pre-ground, since grinding exposes more surface area to air and speeds up the loss of aromatic compounds).
Are pink peppercorns actually a type of pepper?
No — despite the shared "peppercorn" name and similar culinary use, pink peppercorns come from a completely different plant (related to cashews and mangoes) than black, white, and green pepper, which all come from Piper nigrum.
