help maths!!!

hi all im also signed up to another sight like this one ive asked qestions but me an my partner really dont get or understand the answers i know its cheeky but was wondering if anyone here can put it, in more simple terms for me ? the questions and answers ive copied below ….

Unit means a single portion. It is up to you to decide what is your portion size and how many you want to do. For example if you want to use this butter cake recipe to make 50 cup cakes that are 60g each. So the weight per unit is 60, and the number of units is 50. The recipe tool will automatically calculate the amounts for the ingredients in order to make 50 cup cakes at 60 grams each. Back to your question, you have to calculate how many litres are your cakes all together you want to do. This will be your number of unit ( let say 3.5) and how heavy is your cake for 1 litre ( I would say 600g) so 600 is the unit. I hope this helps

Thanks for the reply Serdar, i’m still a bit lost 🙂
The figures in the far right column, are they in grams or what measurement? Also, for the units, is that how many I need? So if i’m doing a 2 tier cake, one 10″ and one 8″ cake, that would be 2 units?
If I want a cake that has 30 slices of 896gms each slice, its gives me a total of 26880 but not sure what unit of measurment it is and says 5998 of sugar?

Hi Angie Thanks for your come back with more questions . I am happy that you don’t give up and give me chance to explain I do not mind to do that till you clear with from confusion.
all weights are in grams . 4535 means 4 kilo 535 gram, 2 means 2 gram
unit means your desired weight of portion in gram
nr of units means how many portion you like to calculate in just a number
So there is no inches sizes or any other measurements can be used for this calculator other than weight in gram and number.
Your request means this: I like to have a recipe that I can make 30 cakes (not slices) each weigh 896 gram before bake and how much I have to prepare . Yes for that big recipe you need 5998 gram sugar .

Going back to your earlier question you have to calculate your each cakes weight by looking at how wide and how high is your cake so you can calculate how many litre is your cake ( rxr x 3.14 x hight). Than you should know how heavy is your 1 litre cake . that means you have your weigh of portion and number of portion.. Lets exercise

Question I like to do 10 inch and 8 inch cake each 3 inch high.
First convert to mm 10 inch 250mm, 8 inch 200mm, 3 inch 75mm
how many litre is 10″x3″ cake ( 250 is R half is r 125)
125×125 x 3.14 x 75 = 3679687.5 mm cubic= 3.67 ltr ( 1 ltr has 1000000mm cubics )
8′ cake
100×100 x 3.14 x 75 = 2355000 so it is 2.35 ltr

all together just 6 litre
I think 1 ltr butter cake is aroung 700 gr if I am not rong.

unit is 700 nr of unit 6

you have to prepare 4200 gr recipe

I hope it helped

Hi AngieS

Yes it does look complicated. To unravel the answer to your question I would need to have the original recipe which that site is using. I don’t feel comfortable with that unless, the recipe is actually in the public domain. If the recipe is freely available to view by everyone and you can send me a link where I can see it, I will try and work out the amount of ingredients you will need for your two tier cake.
However, looking at Mr Yener’s answer, it appears you need to scale up the total quanitity of the original recipe to 4, 200g in total, to make one ten inch round cake and one eight inch round cake, both three inches deep.

Hope this helps.

Hi AngieS

First apologies for keeping you waiting for an answer. I’ve been very busy and your question needs particular attention which I didn’t want to rush through.
I’ve had a look at that recipe on the other site. As far as I can tell, by 1 unit, Mr Yener is referring to a basic quantity of recipe to make one of something. In this case the 1 unit represents 1 round of cake measuring 10″ in diameter (250mm) and 1.5 – 2 inches deep (40 -50 mm). The total quantity as given in the recipe makes 3 such rounds hence 3 units. In fact this is what we would call 3 layers. When stacked you will a cake 4.5 – 6 inches deep plus the fillings. The recipe as you see it is the default and you can change it to any size you want.
Mr Yener is using the standard method of calculating ingredients needed for making large batches of cakes. This method of calculation is used in commercial bakeries. That is why we are finding it difficult to follow. However Mr Yener has given you the answer you need in his penultimate sentence – 4 200g.
As 2, 689g (default) represents the total quantity to bake a 10″ round cake, the total can be used to calculate any other size using our own ready reckoner on this site or Cake Baker’s cakeometer. If using the ready reckoner use 10″ round as your recipe size tin to convert to any other size. If using the cakeometer just fill in the ingredients in the columns and change the settings for whatever size or shape you want. You can find my ready reckoner and Cake Baker’s cakeometer tools here:

What Size cake tin to use

I think for those of us who are used to baking by size of cake and not by volume/density, it is better to follow the calculation methods made by the ready reckoner and by the cake o meter. The mathematics behind the ready reckoner and the cake o meter is the same as that used by Mr Yener. I know this has been a long and winding explanation which I hope has made some sense. If you need more help with conversions using the above tools please post again.
