Since grams are a measure of weight (mass) and milliliters are a measure of volume (capacity), this is not simply a matter of unit conversion. It depends on what you are measuring: 35 grams of lead would take up a much smaller volume than 35 grams of flour. You're not cooking with lead, I know, but even saying "flour" is not specific enough for this purpose. I opened my 1975 edition of "The Joy of Cooking" to the section on conversions and equivalents, and I find that 1 lb of cake flour is 4 3/4 cups, while 1 lb of all- purpose flour is 4 cups. I'll convert those to metric units, using other tables in the same section. 1 cup = 236 ml 1 pound = 454 g Thus, Cake flour: 454 g = 4.75 * 236 ml = 1121 ml 1 g = 1121 / 454 ml = 2.47 ml 35 g = 35 * 2.47 ml = 86.4 ml All-purpose flour: 454 g = 4.00 * 236 ml = 944 ml 1 g = 944 / 454 ml = 2.08 ml 35 g = 35 * 2.08 ml = 72.8 ml Those calculations are probably not as precise as I showed them, because the equivalents in the cook book are not that precise. I hope this helps. - Doctor Rick, The Math Forum http://mathforum.org/dr.math/
