1/2 lb Flour to Cups
1/2 lb of all-purpose flour ≈ 1 3/4 cups (1.81 cups).
That's 226.8 g or 8 oz by weight.
1 full pound of flour ≈ 3 2/3 cups (3.63 cups).
Half a pound of flour shows up a lot in older and bulk recipes that measure by weight. For all-purpose flour, 1/2 lb is about 1 3/4 cups. The exact figure shifts a little with the type of flour, because each one has a slightly different density — the full tables are below.

1/2 lb of Other Common Ingredients
Recipes that weigh the flour often weigh everything else too. Here's 1/2 lb of other staples in cups:
| Ingredient | 1/2 lb = | Rounded |
|---|---|---|
| Butter | 1.00 cup | Exactly 1 cup (2 sticks) |
| Granulated sugar | 1.13 cups | 1 cup + 2 tbsp |
| Brown sugar (packed) | 1.03 cups | ~1 cup |
| Powdered sugar | 1.89 cups | ~1 7/8 cups |
| Cocoa powder | 2.52 cups | 2 1/2 cups |
| Rolled oats | 2.52 cups | 2 1/2 cups |
Why "Half a Pound" Isn't a Fixed Number of Cups
A pound is a unit of weight; a cup is a unit of volume. The bridge between them is density, which differs for every ingredient. That's why 1/2 lb of butter is a tidy 1 cup, but 1/2 lb of airy flour spreads to nearly 1 3/4 cups, and 1/2 lb of cocoa powder reaches 2 1/2 cups. When precision counts, weigh the flour — half a pound is always 226.8 g, no matter how you scoop.

FAQ
How many cups is 1/2 lb of flour?
Half a pound (226.8 g) of all-purpose flour is about 1.81 cups — roughly 1 3/4 cups plus 1 tablespoon. Bread flour is nearly the same, and cake flour, being lighter, comes to about 2 cups.
How many cups is 1 pound of flour?
1 lb of all-purpose flour is about 3.63 cups — close to 3 2/3 cups. That figure comes from 453.6 g per pound divided by 125 g per cup. Bakers often round 1 lb of flour to '3 1/2 to 3 3/4 cups'.
Is 1/2 lb of butter the same as 1 cup?
Yes — almost exactly. 1/2 lb of butter is 226.8 g, and a cup of butter weighs about 227 g, so half a pound of butter equals 1 cup, or 2 standard US sticks. This is one of the few clean pound-to-cup matches.
Why does flour type change the answer?
Density. All-purpose flour is 125 g per cup, bread flour 127 g, whole wheat 130 g, and cake flour only 115 g. The same half pound therefore fills slightly more cups of the lighter cake flour than of the denser whole wheat.
Should I weigh flour instead of using cups?
For baking, yes. A half pound is 226.8 g on a scale — exact every time. Cup measuring varies with how you scoop: spoon-and-level gives ~125 g per cup, but dipping the cup into the bag can pack in 150 g or more, throwing off the recipe.
How many grams and ounces is 1/2 lb?
1/2 lb equals 226.8 g and 8 oz by weight. Don't confuse weight ounces with fluid ounces — 8 oz of flour by weight is about 1 3/4 cups, not 1 cup.
