brown sugar grams to cups Converter

Convert brown sugar grams to cups and back for the brown sugar you actually bake with — packed, spooned or firmly packed — with one tap. Everything runs instantly in your browser; nothing is uploaded.

Convert brown sugar grams ⇄ cups

Grams ≠ cups without the packing — a packed cup of brown sugar weighs far more than a spooned one.
Presets
0.4545 cups
100 g = 0.4545 cups (at 220 g per US cup)

Formula: 100 g ÷ 220 g/cup = 0.4545 cups

Approximate weights: brown sugar weights per cup vary with packing, moisture and brand — the presets are typical values. For baking, weigh with a scale when it matters.

How the brown sugar conversion works

The converter applies cups = grams ÷ grams-per-cup. A US cup is 236.588 ml, and brown sugar's recipe-standard weight is a packed cup of about 220 g — noticeably heavier than granulated sugar's 200 g cup, because the molasses coating makes the crystals clump and pack down.

Worked example: a recipe calling for 200 g of brown sugar needs 200 ÷ 220 ≈ 0.91 cups packed. The same 200 g spooned in without packing would be 200 ÷ 145 ≈ 1.38 cups — same weight, very different volume, which is why recipes assume packed.

Treat every preset as typical, not exact: moisture, brand and how firmly you press all shift the weight. When a bake has to be right, weigh with a scale — and check the packet, which sometimes prints its own cup weight.

brown sugar questions

How many grams are in a cup of brown sugar?
A packed US cup of brown sugar weighs about 220 g — the standard most recipes mean when they say “1 cup brown sugar”. Spooned in without packing, the same cup holds only about 145 g, so always pack it unless the recipe says otherwise.
How many cups is 200 g of brown sugar?
About 0.91 cups packed (200 ÷ 220). If you spoon rather than pack, 200 g is about 1.38 cups — a big difference, which is why packing matters.
Should I pack brown sugar into the cup?
Yes — press it in with the back of a spoon and level the top, unless the recipe says “loosely packed” or “spooned”. Packed is the recipe default, and it is what this converter's 220 g preset assumes.
Is brown sugar heavier than granulated sugar per cup?
Yes. A packed cup of brown sugar is about 220 g, while a cup of granulated sugar is about 200 g — the molasses coating and the packing both add weight.
Can I convert cups of brown sugar back to grams?
Yes — switch the direction above. Grams = cups × grams-per-cup, so 2 packed cups of brown sugar is 2 × 220 = 440 g.
