Enough people have mentioned that they wished I'd posted conversions for the bread recipe that I'm going to do it. Most graduated cup measures have metric conversions, so you probably don't need mine. I measured a kilogram of flour and it was roughly 8 cups. I've read so much about the imprecision of measuring by volume that I didn't want to mess with the perfect kilogram, but it will probably work fine. Just remember, the dough is supposed to be damp.
1 kg flour -- about 8 cups
125 ml water -- slightly more than 1/2 cup (4.4 ounces.)
