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 know how to cook that gravy, that's not the issue. But usually, I take a "normal" pot, chuck in a few onions, and have gravy for a few servings and for the fridge. Pot space was not the issue.

This time, I want to go big. I know that the onions shrink, so what I need to know is with how much onion I should start to get to the stated 10l limit to have enough headroom to stir the stuff.

    Beef shrinks up to 1/2, and onions also shrink up to 1/2 depending on heat.

    Should be easy to figure out.
