How Do I Convert Recipe For An 8 Inch Cake Tin To 9 Inch

Sep 2020: I take updated the calculator to include the instructions on the fields to exist filled in. Cheers Candice for the suggestion!

cake pan conversions — Some of the tins that I brought over with me from Singapore

Recipe calls for a 9-inch cake pan and y'all've only got a vii-inch one? Want to bake brownies in a round pan instead of a square / rectangular one? Or want to broil a bigger cake for a party? These are perhaps some of the common problems that we habitation bakers face considering firstly, many of us cannot afford stocking up different shapes and sizes of baking tins and pans at dwelling due to space and upkeep constraints. And secondly, there may be times when we desire to bake a block in a different size - a bigger cake for a party or just a mini block for that someone special.

Scaling recipes properly and accurately is important because if you try to bake a 7-inch cake in a 9-inch cake pan and follow the blistering times stipulated in the recipe, non only will you get a very sparse and apartment block, yous will also most likely end upward with a burnt block because the cake volition be cooked for way as well long. If you do information technology the other way round - baking a 9-inch cake in a vii-inch cake pan - there will as well much batter and the baking times will exist a lot longer than the one stipulated in the recipe and there is a risk that your cake batter will overflow, leaving a mess in the oven *horrors*.

For me, nigh of the times I need to scale down recipes because I'g baking just for two people these days - if I broil a full recipe, we will have trouble finishing all of the desserts (not to mention the disastrous effects on my waistline). Merely non to worry, this Cake Pan Conversions Calculator is hither to help!

The Formula

The formula used is a very simple and straightforward ane we all learned in school - volume. For round cake pans information technology'due south merely πr²h (π x square of radius x height), for square and rectangular cake pans it'southward lbh (length x latitude x height). I only made information technology easier by combining everything in an Excel document so all we need to do is to 1) choose the type of pan you are converting from and converting to and 2) key in the cake pans' measurements.

The simply key thing to note is to use the aforementioned type of measurements throughout - inches or centimetres. Do not mix them together otherwise the scale factor will not work.

Calibration Factor

Afterward entering the details, there will exist a scale factor in the xanthous box. This scale factor is the number to multiply your ingredients with. Take this calibration factor for example (assuming I used inches for the cake pans dimensions):

Scale factor

So in society to convert a recipe for nine-inch cake pan to my half-dozen-inch cake pan, I need to scale the ingredients down to 0.44. And then the ingredients required for a 6-inch cake pan will exist:

Ingredients	Original Recipe	Scaled Recipe (Multiply everything by 0.44)
Plainly flour Pulley carbohydrate Eggs	200 grams 100 grams 4 eggs	88 grams 44 grams one.76 eggs

Approximation

From the higher up, you volition noted that the scaled recipe requires 1.76 eggs, which is a very weird quantity of eggs. Unless all your ingredients are measured by weights, you volition virtually likely end up with a weird quantity of eggs. So what I will do is to approximate - I will circular upwardly or down the ingredients so that I get something that is easier to work with - in this instance I will most probable circular upwardly the quantities so that I employ 2 eggs for this recipe:

Ingredients	Original Recipe	Scaled Recipe (Multiply everything by 0.44)	Approximation Recipe
Plain flour Caster carbohydrate Eggs	200 grams 100 grams iv eggs	88 grams 44 grams i.76 eggs	100 grams fifty grams two eggs

Special Cake Pans

The formula volition not work for chiffon pans, tube pans, bundt pans or springform pans. Chiffon pans, tube pans and bundt pans take a special design and so the computation of its volume is non as straightforward every bit regular round, square or rectangular cake pans. For the conversion of these cake pans, it volition perchance be ameliorate to apply the infographic from All Recipes.

For springform pans, the formula will piece of work if you are scaling a recipe for springform pans with some other springform pan (i.due east. 9-inch springform pan recipe to a seven-inch springform pan). This is because springform pans usually concur more batter than regular cake pans (not sure why simply obviously that's the case).

And that'south it!

And that is how I calibration most of the cake recipes I found on the cyberspace! I've linked upwardly to the estimator nether the "Recipes" tab, then you lot can access it easily whenever y'all need to. If you would like to download this Excel file to proceed it, you tin grab it here. If you'd like to embed this on your site, you tin can observe the script in the Excel file also.
