These conversions are mostly the U.S. to European conversions for cooking. The European use mostly weight where the U.S. usually use volume. As you could tell, a cup of flour weights different than a cup of water. I hope these conversions are helpful.
The Glossary is converting Spanish to English, English to Spanish, and Spanish of one country or district to Spanish of another. Many areas cook with the same ingredients but call them by some other name. I have tried to gather as many of these names as I could find to help others use the recipes from different areas or countries.
