Converting food measurements from US UK to Metric (Aus)

Hi, I am writing a scaling recipe workbook that converts US UK measures to metrics (Aus). The formula to convert the measures works.

IF($J11="Eggs",$AA11/12,($AA11*XLOOKUP($H11,rngRecipeMeasure,Conversion_Factor,$H11,0))) ` this works

But I also want to convert "each" eggs to dozen if there are more than 12 eggs

can I combine the 2 formulae and if there is another measure bring that up or another "each" and leave it as each.

I am stuck
