You just put what you find cringy
(This does not include the weight of a shulker box to avoid confusion) If the gold block is the heaviest block, and gold armor is the heaviest armor. If you took shulker boxes, each completely filled w/ stacks of 64 gold blocks, and put them in every slot of your inventory including offhand and put on armor, then here's what your carrying: 42,509 lbs (19,282.2 kg) for 1 gold block, 27 slots in shulker box, 37 slots in inventory, 600 (271.92 kg) lbs for all pieces of armor, 2,644,400,472 lbs (1232827011.12 kg) total for how much Steve (or Alex) can carry at once. Wow. But then again, using another method, you get more than the entire universe in a single chest.
