The above conversion list is for your guidance only, variations in temperature can be expected during the cooking period, but, if you follow your recipe correctly, this should not affect the finished result. If using a fan oven, many cooking times can be reduced by approximately one third e.g. in some cakes and pastries, please see oven manual for more details.

List of abbreviations.
fl.oz, fluid ounce
I very much hope that this section will act as a quick reference to help American cooks out when looking for that necessary vital item either for a recipe or in food preparation. Items are listed as follows: British/Australian, followed by its American equivalent.
Converting British weights and measures to American
There are sometimes significant differences between the measures used for ingredients in British and American recipes. For example a British standard tablespoon holds 17.7ml while the American tablespoon has a 14.2 ml capacity.
Similarly a British pint measures 20 fluid ounces while an American pint is just 16 fluid ounces.
The standard American measuring cups sold here in the UK are one 4 ounce cup and smaller, Many American recipes use an 8 ounce (two cup) as a basis for measuring recipe ingredients. Bear in mind that the same cup measures differently for liquid and dry, depending on the weight of the ingredient, i.e. flour, breadcrumbs and oatmeal will be 4 oz, (110 g), but sugar, butter, dried fruit, chopped vegetables, syrup etc., will weigh differently.
The listings below should enable recipes to be successfully made by American cooks. The only advice I would offer, having spent hours trawling websites and reading through books for factual information, hints and tips, is, to be consistent, never mix imperial, metric or cup measures in one recipe, If you use the same measuring system throughout, your dishes should work out correctly. If in doubt, weighing is still the most reliable and much preferred method to use, even by many American cooks.
Purchasing a good set of balance scales with either metric or imperial weights, really will eliminate any guesswork and give good, consistent results every time.

Baking tins, a useful conversion.
There may be occasions when the exact size of a baking tin may not be available or when you wish to make a particular cake recipe in another shape. The following conversions might prove useful. For the purposes of baking, the capacity of a round cake tin is equal to that of a square cake tin that is 2.5cm, one inch smaller in size, for example a 20cm/8inch round tin holds the same quantity as an 18cm/7inch square tin.
British = American
An 800ml/11/2pint pudding basin = a 14cm/ 51/2 inch round deep cake tin.
A 1.2 litre/2 pint pudding basin = a 15cm/6" round deep cake tin, or a 12.5 cm/5" square deep tin.
A 1kg/2lb loaf tin = an 18cm/7inch square shallow cake tin or a 33 x 23 cm/13 x 9 inch Swiss roll tin.
