OK, he is frustrated, I get that. However, he goes out of his way to be confused by American volumetric measure issues which can be cleaned up by better research. A few points, commenting ONLY on American measure. *Measuring cups and spoons have well defined volumes, "common" cups and spoons (real expresso, tea and coffee cups, real flatware) don't. Use measuring cups and spoons to measure. *1 US gallon = 128 fl oz = 3.785 411 784 L, exactly. NIST Handbook 44, Appendix C defines the cup as 8 fl oz, the Tablespoon as 0.5 fl oz, and the teaspoon as 1/3 Tablespoon. These values are (rounded slightly) 236.5882 mL, 14.786 76 mL, 4.928 922 mL (from NIST SP811). *Rounded values of 240 mL, 15 mL, 5 mL are specified by law ONLY for serving sizes in the nutrition label (specified by FDA), and are NOT accurate enough for net contents labels (specified by FTC). They are probably "good enough" in the kitchen, but it should be understood they are rounded. Measuring Tablespoons are commonly marked 1 Tbsp / 15 mL; it is not clear whether they are really 15 mL or nearer 14.79 mL, but it probably doesn't matter in cooking. He is welcome to remain as confused as he wishes to be, but his questions have answers. It does seem that elsewhere, volumetric cooking measure is not as well defined, probably because they don't use it anymore.
