Halving or doubling a recipe that cooks in a skillet or saucepan is no problem but in baking it is. How would you double or half a recipe that calls for a 9"x9" baking pan. That is 81 square inches and to half or double it would require about 40 sq inches or 160 sq inches in order to keep the same depth in what you are baking or else your times and temps would be off. Am I the only one that tries to change the amounts or do that make pans the have volumes. I've even tried working out volumes in round pans with the Pi(R)2 thingy, (Pi still is 3.14 is it not) but can't get anything to work.

I usually just use a 4 or ? cup measure and fill it with water and divide or multiply that amount????
I am pretty good with math, but that is quicker. I have a conversion chart here somewhere if I can find it??

I entered "conversation chart for different sized baking pans" in the search. You will get many, many more and lots of other good info more.

Good Luck,

If you have an unusual pan size, and would like to find out the capacity, measure the amount of water it takes to fill the pan. Then compare it with the pans above to determine the substitution. For your cake to rise evenly, you should only fill this pan to the half-way mark with batter. The baking time may change as well, so it is imperative that you keep a watchful eye on your cake, and check for doneness using your preferred method.
