Use this helpful guide to find baking and cooking conversions between metric, imperial and US cup measures.
For most home cooks, an extra gram or two of an ingredient won't make much of a difference. Once you start working with larger quantities, however, precision counts: an incorrect measurement can throw off a ratio and ruin a recipe. Proper ingredient measurements are especially important in baking. If you're working with larger quantities, especially in baking, seek out a precise conversion tool on the internet, or use a search engine to convert between metric and imperial.
