Conversion Tables are a really useful planning tool when you are not used to working in the stated weights and measures or temperatures. Remember these are only a guide!

Oven temperature
All ovens vary and your oven will have its own unique heat pattern and quirks! Electric fan ovens tend to be the most consistent but even these will not be calibrated so although the conversions below are correct your oven may be up to 10 Celsius warmer or cooler. Know your oven!

Grams to ounces
I would strongly recommend working in grams. However it is useful to know the approximate conversion – particularly when you are used to working in another measure and when purchasing ingredients when grams is not shown on the packet. The table below shows approximate conversions.

Millilitres to fluid ounces
I would strongly recommend working in millilitres. However it is useful to know the approximate conversion – particularly when you are used to working in another measure and when purchasing ingredients when millilitres are not shown on the bottle. The table below shows approximate conversions.

Cake tins
Very roughly a square tin holds approximately 25% more than a round tin of the same diameter. If you’re using a square tin where a round tin is stated in the recipe, keep the temperature the same, and turn the cake during baking, as the corners tend to cook faster than the middle.
