Why is a quart of flour not 32 ounces?

Fluid ounces measure volume, so every quart holds the same number of them whatever you pour in. On a kitchen scale, the numbers scatter: USDA data puts a quart of all-purpose flour at about 17.6 ounces, granulated sugar at 28.2 ounces, and whole milk at 34.4 ounces.

Even water weighs a little more than its fluid ounce count, at 33.4 ounces per quart. For recipes written by weight, the quarts to pounds converter lets you pick the ingredient.

Does 1 quart equal 4 cups?

Yes, in US measure a quart is 4 cups. Each of those cups holds 8 fluid ounces, which is where the quart's ounce count comes from. With metric cups of 250 ml, a quart is 3.785 cups instead.
