About the Pounds to Cups — Brown Sugar (packed)
This is the one measurement where recipes genuinely mean "compress it". Packed brown sugar is pressed firmly into the cup so it holds the shape when tipped out; loosely spooned it weighs closer to 145 g, a third less. If a recipe does not say packed, it almost certainly still means packed. The molasses content is what makes it clump — it is also what makes it weigh more than white sugar. The figure this page works from is 213 g per US cup, the spooned-and-levelled weight recorded by King Arthur Baking and the USDA food database. Converting pound to us cup for brown sugar, the amounts that come up most often are: 1/4 pound = 0.532 us cup; 1/2 pound = 1.06 us cup; 3/4 pound = 1.6 us cup; 1 pound = 2.13 us cup; 1 1/2 pound = 3.19 us cup; 2 pound = 4.26 us cup; 2 1/2 pound = 5.32 us cup; 3 pound = 6.39 us cup; 5 pound = 10.6 us cup.
What people use it for
- Following a US recipe with a kitchen scale instead of cup measures.
- Scaling a recipe up or down without compounding measuring error.
- Converting a European recipe written in grams into cups.

The maths behind it
This tool uses us cup = pound × 2.1295416432, derived from brown sugar weighing 213 g per US cup. Every intermediate value is shown on screen, so the result can be checked by hand.
This is the one measurement where recipes genuinely mean "compress it". Packed brown sugar is pressed firmly into the cup so it holds the shape when tipped out; loosely spooned it weighs closer to 145 g, a third less. If a recipe does not say packed, it almost certainly still means packed.
Where this tool stops
Volume-to-weight conversion is inherently approximate. Humidity, brand, how finely something is milled and how long it has sat in the cupboard all shift the figure by a few per cent.
Frequently asked questions
What does "packed" actually mean?
Press the sugar into the cup with the back of a spoon until it is firm, then level the top. Tipped out, it should hold the cup's shape briefly. Anything looser and you are using roughly a third less sugar than the recipe intended.
Why does a cup of brown sugar not weigh the same as a cup of water?
Because a cup measures volume and a scale measures weight, and the two only agree for water. Brown sugar has its own density — 213 g per US cup — so any generic volume converter gives the wrong answer here.
How much does the way I fill the cup matter?
Completely, and here the recipe is asking you to compact it on purpose. "Packed" means pressed firmly enough to hold the cup's shape when tipped out, which gives the 213 g used here. Spooned in loosely the same cup holds closer to 145 g — a third less sugar, and a noticeably drier, paler result.
Is a US cup the same as a UK or metric cup?
No. A US cup is 236.6 ml, a metric cup is 250 ml and an old UK cup is 284 ml. These pages use the US cup, because that is what US recipes mean.

When is the Pounds to Cups — Brown Sugar (packed) not the right tool?
