I plan to make a BIG pot of onion gravy soon. Is there a rule of thumb about the volume and weight relation of sliced onions?

So, my big pot holds about 12l - I’d go for 10l here to have room to stir - if thinly sliced on a mandolin, how many kilograms of onions would that be?

Or, the other way round, if one slices a kilogram of onions, how much volume would that fill?

    I make an onion pasta sauce in a Dutch oven the same size. If it’s just onions (sliced as like 3 cm x 1 cm slices) I can fill the pot, and it’s pretty much half the volume or less when fully cooked. But it is like an all day cook to essentially make an onion pasta.
