This is a project I've been thinking about doing for years and am finally starting.

I'm building an Excel spreadsheet that lists every item in the kitchen (pans, bowls, etc) along with its dimensions, weight, and (where appropriate) capacity, to the fill line, not the brim. (Not sure it makes sense to measure the capacity of a 15x21x1 sheet pan, but I'll probably estimate it.)

This way I know the capacity of all my pots and bowls, and their empty weight, so if I want to know how much I've got in a pan, I can weight it and subtract the empty weight.

I'm finding that there's a fair amount of variance in the weight of essentially identical items, like custard cups, so I'm showing the range where significant.

When I'm done I'll post the most commonly used items on a cabinet door and the full list will go in my recipe notebook.

Here's a short sample:
