Why do red kidney beans come in 410g cans?

I live in a fully metric country. Every single canned vegetable or pulse comes in a nice round number - and generally 400g of it.
Except for red kidney beans - they always come in 410g cans. And every single recipe I've found always calls for a 410g can. I've searched for this question and all I found was links to shopping sites selling - you guessed it - 410g red kidney beans - so I'm assuming it's across the board.
So why the extra 10g tacked on the end?
Best Answer
Perhaps because the cans are of a standard height and the extra 10g of beans gives the proper headspace in the can?
