# Welcome to the Cake Decorators Q&A

## ingrediants

hi , might sound a daft question but here goes. If I have say a 6inch recipe , how do I work out the quantaties for say an 8inch tin, 10inch tin and so on .

Hi dinky, last post was lost in space, here is the mathematical formula. This is my hubby’s conversion for me. He is a scientist so has had to use all sorts of formulae in his work.

## How to convert a cake recipe from one tin size to another

There must be a science behind it so happy for anyone to add something more constructive but here goes….

Just through trial and error we’ve worked out just through basing everything on how many 10″ cakes we get from a mix and doing some very rough maths from that. Strangely though it never seems to work exactly the same every time – now that is one for the scientists.

Google lindy smiths conversion chart (it’s on her website). She explains how to multiply to work out for different sizes of tins

hmmm. thanks david thought it might be trial and error.

and thanks jmilne I will have a look at lindy smith

Hi dinky, I posted the mathematical formula on here last night but for some reason it hasn’t appeared. Using wifi at the moment, may be that is why it is delayed. Keep an eye out for it, this is not the first time it has happened. Will post again if it has been lost in space!

thanks madeitwithlove, not got it yet

hi madeitwithlove, sorry not replied earlier. my coputer broke. I found this hard to follow. I have gone with the lindy smith conversion chart. thanks anyway

Thanks, madeitwithlove! I’ll be far more confident attempting conversions knowing why I’m using a particular conversion factor. If that doesn’t explain how much I appreciate your formula post, I’ll try a simpler way: Thank you, thank you, thank you!!! *Hugs* .^_^.

Hello darlinghuskey

You can also easily make conversions here http://www.cakeflix.com/blog/how-to-work-out-what-size-cake-tin-to-use

Both the ready reckoner or the the cakeometre are simple tools to use but as you say knowing the formula does give confidence. x
