Knowing how to convert between pounds and cups is an essential skill for bakers, chefs, and home cooks. Whether you’re trying to halve a recipe, double a batch of cookies, or simply measure out the correct amount of flour, it’s important to understand the relationship between pounds and cups. In this comprehensive guide, we’ll walk through everything you need to know to easily convert between pounds and cups of common baking ingredients like flour, sugar, and butter. We’ll also provide some quick reference charts and a step-by-step example to help you master kitchen conversions. So read on to become a pro at converting pounds to cups and vice versa!
Quick Answer
1 1/2 pounds is approximately 6 cups. More specifically, 1 pound equals 4 cups while 1/2 pound equals 2 cups. By adding these together, 1 1/2 pounds equals 6 cups total.
Pounds to Cups Conversion
Many baking recipes call for ingredients by weight in pounds, while measuring cups are more convenient for most home bakers. So it’s helpful to have a solid understanding of how to convert between the two units of measurement. Here are some key facts about converting pounds to cups:
- 1 pound (lb) equals 4 cups (c)
- 2 pounds equals 8 cups
- 1/2 pound equals 2 cups
- 1/4 pound equals 1 cup
As you can see, the pounds to cups conversion is fairly straightforward – you simply multiply the number of pounds by 4 to get the equivalent number of cups. For example:
- 2 lbs = 8 cups
- 1.5 lbs = 6 cups
- 0.5 lb = 2 cups
Keep in mind that while this conversion is quite accurate for most baking ingredients, it is still an approximation. The exact cups per pound varies slightly for ingredients like flour, sugar, butter, etc. We’ll take a closer look at converting common ingredients in the next section.
Cups to Pounds Conversion
Going the opposite direction from cups to pounds is just as easy. Simply divide the number of cups by 4 to convert to pounds. For example:
- 8 cups = 2 lbs
- 6 cups = 1.5 lbs
- 2 cups = 0.5 lb
Again, this cups to pounds conversion will work perfectly for most baking scenarios. But the exact pounds per cup can vary a bit depending on the ingredient.
Pounds to Cups Conversion By Ingredient
While the general 4 cups per pound conversion applies to most baking ingredients, the exact ratio can vary slightly depending on the density and fineness of the ingredient. Here is a more accurate pounds to cups conversion for common baking ingredients:
Flour
- 1 lb flour = 3.75 cups
- 2 lbs flour = 7.5 cups
- 0.5 lb flour = approx 2 cups
Since flour tends to settle and become compacted, you typically get slightly less than 4 cups per pound. All-purpose flour and cake flour have about 3.75 cups per pound. Whole wheat flour is lighter so has closer to 4 cups per pound.
Sugar
- 1 lb granulated sugar = 2 cups
- 1 lb confectioners’ sugar = 4 cups
- 1 lb brown sugar = 2.25 cups (packed)
Granulated and brown sugars have a coarse texture so 2 cups or less per pound. Confectioners’ sugar is much finer so you get 4 cups per pound. Always pack brown sugar tightly when measuring.
Butter
- 1 lb butter = 2 cups
- 0.5 lb (1 stick) butter = 1 cup
Butter is densely packed so you only get 2 cups per pound. Each stick of butter (0.5 lb) equals 1 cup.
Cocoa Powder
- 1 lb cocoa powder = 3 cups
Cocoa powder is lightweight and fluffy so you get more cups per pound.
As you can see, granulated sugar, brown sugar, and butter all have around 2 cups per pound. Flour and cocoa powder are closer to 4 cups per pound. So factor in the specific ingredient when converting pounds to cups for the most accuracy.
Pounds to Cup Example Conversion
Let’s walk through an example baking recipe conversion from pounds to cups:
A cookie recipe calls for:
- 2 lbs flour
- 1 lb granulated sugar
- 1 lb butter
- 1/2 lb cocoa powder
To convert to cups it would be:
- 2 lbs flour x 3.75 cups/lb = 7.5 cups flour
- 1 lb granulated sugar x 2 cups/lb = 2 cups sugar
- 1 lb butter x 2 cups/lb = 2 cups butter
- 0.5 lb cocoa powder x 3 cups/lb = 1.5 cups cocoa powder
So in cups the recipe requires:
- 7.5 cups flour
- 2 cups sugar
- 2 cups butter
- 1.5 cups cocoa powder
You can see how using the accurate cups per pound conversions results in different cup measurements than the generic 4 cups per pound conversion. Taking the specific ingredient densities into account helps ensure the highest accuracy when converting pound recipes to cups.
Cups to Pounds Conversion Table
For quick reference, here is a conversion table for the most common baking ingredients:
| Ingredient | Cups per Pound | Pounds per Cup |
|---|---|---|
| All-purpose flour | 3.75 cups | 0.27 lb |
| Granulated sugar | 2 cups | 0.5 lb |
| Confectioners’ sugar | 4 cups | 0.25 lb |
| Brown sugar | 2.25 cups (packed) | 0.44 lb |
| Butter | 2 cups | 0.5 lb |
| Cocoa powder | 3 cups | 0.33 lb |
This makes it easy to quickly find the conversion in either direction. For example:
– If you need to convert 1.5 cups all-purpose flour to pounds – look up flour in the table and see it’s 0.27 lb per cup. So 1.5 cups x 0.27 lb/cup = 0.41 pounds.
– To convert 0.5 lb cocoa powder to cups – cocoa powder has 3 cups per pound, so 0.5 lb x 3 cups/lb = 1.5 cups

Tips for Accurate Pounds to Cups Conversions
Here are some top tips to ensure accuracy when converting pound and cup baking measurements:
- Use a digital kitchen scale – Weighing ingredients yields far more accurate results than trying to approximate cup conversions from pounds.
- Level off ingredients after scooping – Use a straight edge like a knife to level off dry ingredients for an exact cup measurement.
- Pack brown sugar tightly – Always pack brown sugar firmly into the cup measure for an accurate conversion.
- Spoon flour lightly – Spoon flour loosely into the cup rather than scooping to avoid excessive compaction.
- Butter equals 1 cup per stick – One stick of butter (1/2 cup) always equals 1 cup for easy reference.
Following these best practices will ensure your baked goods come out perfectly no matter which units the recipe uses!
