In short
One pound of granulated sugar is 2.26796185 us cup. Going the other way, one us cup is 0.4409245244 pound. That works out at 2 pound = 4.5359237 us cup and 4 = 9.0718474. The figure comes from granulated sugar weighing 200 g per US cup — a generic cups-to-grams converter assumes water and will give you the wrong answer here, because volume to weight depends entirely on what is in the cup.

About the Pounds to Cups — Granulated Sugar
Granulated sugar is one of the few dry ingredients where scooping is fine — the crystals do not compact meaningfully, so the cup weight is consistent however you fill it. That is why sugar measurements vary far less between recipes than flour measurements do. Caster and superfine sugar weigh very close to the same per cup; the crystal size differs, not the density. The figure this page works from is 200 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 granulated sugar, the amounts that come up most often are: 1/4 pound = 0.567 us cup; 1/2 pound = 1.13 us cup; 3/4 pound = 1.7 us cup; 1 pound = 2.27 us cup; 1 1/2 pound = 3.4 us cup; 2 pound = 4.54 us cup; 2 1/2 pound = 5.67 us cup; 3 pound = 6.8 us cup; 5 pound = 11.3 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 × 2.26796185, derived from granulated sugar weighing 200 g per US cup. Every intermediate value is shown on screen, so the result can be checked by hand.
Granulated sugar is one of the few dry ingredients where scooping is fine — the crystals do not compact meaningfully, so the cup weight is consistent however you fill it. That is why sugar measurements vary far less between recipes than flour measurements do.
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
Does caster sugar weigh the same as granulated?
Near enough. Caster is granulated sugar ground finer, so a cup lands within a few grams. Use the same weight and expect it to dissolve faster, which is exactly why caster is preferred in meringues and creamed batters.
Why does a cup of granulated 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. Granulated sugar has its own density — 200 g per US cup — so any generic volume converter gives the wrong answer here.
How much does the way I fill the cup matter?
Barely at all, and granulated sugar is one of the few dry ingredients you can genuinely scoop. The crystals are hard and roughly uniform, so they do not compress — a cup lands near 200 g however you fill it. That consistency is why sugar quantities vary far less between recipes than flour quantities do.
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.
Is the Pounds to Cups — Granulated Sugar free, or is there a paid tier?
Free, unlimited, and no email address required. You can use it a hundred times a day and nothing changes.

What do I get if I try it?
Enter 2 pound of granulated sugar and the Pounds to Cups — Granulated Sugar returns 4.5359237 us cup.
What do people use the Pounds to Cups — Granulated Sugar for most?
The jobs it is built 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. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
When is the Pounds to Cups — Granulated Sugar not the right tool?
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. Knowing where a tool stops being trustworthy matters more than the cases where it works.
Which values should I know?
1 US cup of granulated sugar is 200 g. 1 Pound is 2.26796185 US cup. 1 US cup is 0.4409245244 Pound. These are printed on the page itself, so you do not have to take them on trust.
