    The reason 8 oz of flour is different than 8 oz of liquid is they are completely different. A cup is a measure of volume only while ounces are measured by volume and by weight. Measure solids by weight and liquids by volume.

    You can measure the weight of 1 cup of flour 3 times and get 3 weights. If you fill a cup then tap it on the countertop, you will create more space at the top by packing the flour down. Then you have less than a cup of flour, so you'll add more flour until the cup is full. The more loosely packed, the more air in the cup (which weighs zero but occupies space). A packed cup of flour will weigh significantly more than a loosely packed cup and neither will weigh the same as a cup of water, which does not weigh the same as a cup of oil or milk.

    Therefore when you see a reference to "one cup of flour" it is an approximation. You cannot measure ounces of a solid in a measuring cup for volume of liquid.

    You're right - baking is chemistry, and it's all about precise weights and measures.
