Is there such a thing as a pellet use chart?

Hello folks,
Is there such a thing as a pellet use chart?
If not clear, what I'm trying to determine is how many pellets does it take to cook a brisket at say 12 hours at 225. Any kind of chart exist that show time vs temp = amount of pellets needed to cook?
Thanks folks
Woody
