Convert sugar grams ⇄ cups

Grams ≠ cups without the ingredient — a cup of sugar weighs differently from a cup of flour.
Presets
0.5 cups
100 g = 0.5 cups (at 200 g per US cup)

Formula: 100 g ÷ 200 g/cup = 0.5 cups

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

How the sugar conversion works

The converter applies cups = grams ÷ grams-per-cup. A US cup is 236.588 ml, so a cup of granulated sugar at a typical weight lands on 200 g — finer or coarser sugars pack differently, which is why this page has a preset per type.

Worked example: a recipe calling for 150 g of granulated sugar needs 150 ÷ 200 = 0.75 cups. The same 150 g of powdered sugar is 150 ÷ 120 = 1.25 cups — same weight, far more volume, because powdered sugar is mostly air.

Treat every preset as typical, not exact: brown sugar's weight depends on how firmly it is packed, and powdered sugar settles in the bag. When a bake has to be right, weigh with a scale — and check the packet, which sometimes prints its own cup weight.

Quick reference

  • 50 g granulated sugar — 0.25 cups
  • 100 g granulated sugar — 0.5 cups
  • 150 g granulated sugar — 0.75 cups
  • 200 g granulated sugar — 1 cup
  • 250 g granulated sugar — 1.25 cups
  • 400 g granulated sugar — 2 cups

sugar questions

How many cups is 200 g of sugar?
Exactly 1 cup of granulated sugar (200 ÷ 200). The same 200 g of caster sugar is about 0.89 cups, and of powdered sugar about 1.67 cups — the type matters.
How do I convert sugar grams to cups?
Divide grams by the sugar's weight per US cup: cups = grams ÷ grams-per-cup. With the granulated preset selected above, type any weight to see it — or switch direction to go from cups back to grams.
Does brown sugar weigh the same per cup as white sugar?
No. Brown sugar is usually packed into the cup, so a packed cup weighs about 220 g against granulated sugar's 200 g. Loosely spooned brown sugar weighs less — another reason to weigh rather than scoop.
How many grams are in a cup of sugar?
Typical values: granulated 200 g, caster 225 g, brown (packed) 220 g and powdered 120 g. Brand and packing shift these a little, so treat them as typical, not exact.
Can I convert cups of sugar back to grams?
Yes — switch the direction above. Grams = cups × grams-per-cup, so 1.5 cups of granulated sugar is 1.5 × 200 = 300 g.
