How do I measure brown sugar for this converter?

Brown sugar should be firmly packed into the measuring cup so that it holds its shape when turned out. This is the standard method assumed by virtually all recipes and by this converter. Loosely spooned brown sugar weighs significantly less and will give you inaccurate results.

Does light brown sugar weigh the same as dark brown sugar?

Yes. Both are measured packed, giving them the same density of approximately 220 grams per cup. Dark brown sugar contains more molasses, which affects its flavor and moisture, but not its packed weight.

How many grams is 1 cup of brown sugar?

One packed cup of light or dark brown sugar weighs approximately 220 grams (about 7.76 ounces). This is slightly more than granulated white sugar (200 g/cup) because packing compresses the crystals.

How many grams is 1 tablespoon of brown sugar?

One packed tablespoon of brown sugar weighs approximately 13.75 grams. There are 16 tablespoons in a cup, so 220 g divided by 16 equals about 13.75 g per tablespoon.

Can I substitute light brown sugar for dark brown sugar by weight?

Yes, you can substitute them 1:1 by weight. The flavor will differ slightly — dark brown sugar has a more intense molasses taste — but the texture and structure of your baked goods will remain essentially the same.

Why is weighing brown sugar more accurate than measuring by volume?

The amount of brown sugar that fits in a cup varies depending on how tightly it is packed. Weighing eliminates this variability entirely, ensuring you add exactly the same amount every time regardless of who packs the cup.
