switching pans on a cake recipe-need help!

[trolley]

I have a recipe for a yellow cake that yields three 9" round cakes. I'd like to make this recipe in a 9x13 sheet cake. do i need two 9x13 or would it all fir into one 9x13? it looks like it may since a 9x13 seems so big! it also bakes for 20-25 minutes. i'm assuming i'd bake it for a tad bit longer...any ideas?

I found this conversion chart which says that a 9 by 1.5" pan takes 6 cups of batter and a 9 by 2" pan takes 8 cups, while a 9 by 13" takes 14 cups. So you should be able to fit it all in one 9 by 13" and have leftover (cupcakes?!). It will take a little longer to bake. It's probably advisable to lower the oven temp a little bit, but I can't say how much...

can you please tell me where you found this conversion chart? i feel like i need to go to a baking specific site to ask this question.

Yes! That's the one--I meant to put up the link but it was about 2:00 am and I wasn't exactly at my sharpest.
