### Converting Grams to Milliliters

I need to know how many ml you would get out of 35g of flour?  I'm not
sure how to do that.

Hi, Sue.

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.
