Is there a similar ratio when brewing with all grain.
Yes. But until you know your own efficiency, you'll have to guestimate for the first batch (and probably the second).
I get a steady 72% efficiency. But others get 65%, while others get 85%. You can make your first recipe at 68% to guestimate it, and adjust the next batches.
