Weight Conversions

It is difficult to give an exact conversion for grams and ounces as 1 oz = 28.35g.  So do not mix and match imperial with metric in recipes.

Volume / Liquid Conversions

Although an American fluid ounce is the same as a British fluid ounce, in weight and volume, the size of our pints is different.  In the States  there are 16 fluid ounces in a pint, where as in the UK there are 20 fluid ounces.
