This list is not exhaustive for all your cooking needs, but it should help you with trying to work with when adapting between various American units of measure, and working out oven temperatures between different heat types. Measurements Conversion Calculator, an on-line resource, will also assist you to convert recipes between American units and metric ones.
One other thing to consider is that U.S. and UK imperial measurements in older recipes might not be referring to the same volume. Of course, one of my big recommendations to everyone, especially for those who bake, is to use a kitchen scale. I rely on mine most of the time, even if I do have cups, teaspoons, etc. on hand.
