In Reply to: Conversion of 10 posted by Vera on February 09, 1998 at 11:12:00:
: I need to convert a cake recipe from a 10" cake pan to a full sheet. Please help.
There's some bakers percentage yield formula, and most bakers scale out their cake batters, but I'm assuming you're using a home cook's cake recipe, which is just another excuse for me to use algebra and geometry.
Calculate the volume of your sheet pan (if 18 x 24 x 1, it's 432 cu. in.) The volume of your 10" cake pan, if 2" high, is 157 cu. in.
volume of sheet pan, divided by volume of round pan = multiplier
432 / 157 = 2.75 +/-
So multiply your recipe by 2.75
