Amount of mixture per tin
I have to make 6 different sized single layer cakes using victoria sandwich mix. Can anyone please help me with what weight of mixture needs to be in each tin for an even depth. Tins are 13,11,9,7,5 and 3 inches. Is there perhaps a magic formula, such as x grms to y cms/ins per tin. Thank you

If you measure how much your mix increases in volume from raw to baked, you can figure out what volume to start with in order to get X finished volume. Then, measure the volume of you tins and you can calculate the volume of raw mix to use that will result in a full tin when baked.
If you want / expect part of the baked mix to protrude above the level of the tin, the volume above has to be factored in as well.
Assuming that each tin would rise the same amount (not sure why they wouldn't), you just need to start with the same level/depth of mix in each tin.
So, take the 3" tin and fill it with water to the level that you would have the mix at, pre-bake. Measure that volume of water. That is V, your starting point.
The 5" tin would then have 2.75 times the volume of the 3" tin (2.75*V) to have the same starting level of mix.
The 7" tin would have 5.5 times the volume (5.5*V)
The 9" tin would have 9 times the volume (9*V)
The 11" tin would need 13.5 times the volume (13.5*V)
The 13" tin would need 18.75 times the volume (18.75*V)
So, the total volume of mix you would need is 50.5 times whatever volume you find for the 3" tin.
I guess you might have to make up one batch of the mix and measure the volume that you get, so you will know how much mix you'll need to get the the right total volume.
This was all back-of-the-envelope calculations early in the morning, so you might want to try filling each of the tins to the same level and then measuring each volume. Just in case! :-)
Good luck
