Lady Penelope, the best thing might be to get a set of measuring cups and measuring spoons from the US. Then you wouldn't need to worry about conversions. If you have a friend here, maybe that person could send them to you. At stores they are available in a variety of prices so they needn't be a big expense for your friend. They are also available online, but most websites I looked at have fairly high prices. I recommend getting a set of measuring spoons (1 tablespoon, 1 teaspoon, 1/2 teaspoon, 1/4 teaspoon), a set of measuring cups for solids (1 cup, 1/2 cup, 1/3 cup, 1/4 cup), and a 2-cup transparent measuring cup for liquids. It will indicate measurements for less than 2 cups, including fractions of a cup. The reason for having different cups for solids and liquids is that in a clear liquid cup you can easily check the volume by placing the cup on a level surface, but with solids you first fill the cup and then slide the edge of a knife or spatula across the top to remove any excess. In the US most of the liquid measuring cups have US measuring marks on one side and metric marks on the other. If this is true in the UK, too, you might not need one. When the US was thinking of "going metric," lots of people got all upset. I told them they could hang on to their old cookbooks and measuring devices, get new cookbooks and measuring devices, or do both.That's much easier than doing conversions. If you need to convert things, including a stick of butter and oven temperatures, this website might help: http://www.onlineconversion.com/cooking.htm
