Flour is one of the trickiest ingredients to convert between grams and milliliters. With a density of about 0.60 g/ml, flour is much lighter than water — 100 grams of flour fills approximately 167 ml. The exact density depends on whether the flour is sifted, packed, or spooned.
Getting flour measurements right matters in baking. Too much flour makes bread dense; too little makes cakes fall flat. Use our gram to ml converter for accurate flour conversions every time.
