  • These figures use the US cup (240 ml). A metric cup is slightly larger at 250 ml, so it holds a little more. Use the metric cup converter →
  • Cup sizes are not standard worldwide, so the same cup of an ingredient can weigh more or less depending on the country. What is a cup measurement →
  • Brown sugar is measured packed, so a cup's weight depends on how firmly you press it. This page uses 220 g for a firmly packed metric cup, the figure most recipes assume. Lightly packed it drops to about 200 g. Weigh for the most reliable result.

Brown sugar is a soft, moist sugar that contains molasses, giving it a rich color and a deeper, caramel-like flavor. It comes in light and dark varieties and is commonly used in cookies, sauces, marinades, and baked goods. Depending on where you are in the world, it may also be called soft brown sugar, light muscovado, or demerara (though demerara has larger crystals).

As brown sugar packs differently in measuring cups, it’s especially helpful to convert it by weight for accuracy. This page provides simple conversions between grams, cups, tablespoons, and more to help you get consistent results in any recipe.

  • Light Muscovado
  • Demerara
  • Soft Brown Sugar

White granulated sugar is drier and lighter packed than brown sugar (200 g vs 220 g per cup) and has no molasses flavour. Swapping it in loses the moisture and caramel notes, so weigh when substituting and expect a crisper, plainer result. See our Sugar converter.

Raw sugar is dry with hard crystals and only a trace of molasses, unlike soft, moist brown sugar. It packs lighter (200 g vs 220 g per cup), so weigh when swapping and expect a drier, crunchier result. See our Raw Sugar converter.

Molasses is the syrup that gives brown sugar its colour and caramel flavour. You can add a small amount of molasses to white sugar as a substitute for brown sugar, though the result will be wetter and more intensely flavoured. See our Molasses converter.

Palm sugar has a similar caramel depth to brown sugar but a deeper, earthier flavour from the palm sap. It weighs slightly less per cup (200 g vs 220 g), so weigh when swapping and adjust to taste. See our Palm Sugar converter.
