# How much does 1 2 cup of packed brown sugar weigh?

Brown sugar is a very common baking ingredient used to add sweetness and moisture to baked goods like cookies, cakes, muffins and more. When measuring brown sugar for recipes, it’s important to know that you should always pack the brown sugar tightly into the measuring cup to get an accurate measurement. This ensures you have the right amount of brown sugar by volume to achieve the intended flavor and texture in a recipe. So how much does 1 2/3 cups of tightly packed brown sugar actually weigh? Let’s take a closer look.

## The Weight of a Cup of Brown Sugar

Brown sugar is composed of white granulated sugar combined with molasses, which gives it its characteristic brown color and moist, soft texture. The molasses content can vary between 3.5% to 6.5% depending on whether it is light or dark brown sugar. Since the molasses adds weight, brown sugar is denser and heavier than white sugar when measured by volume.

Most recipes provide brown sugar amounts by volume measurements in cups or fractions of cups. But it can be useful to know the weight equivalent for scaling or adapting recipes. Here is the approximate weight of brown sugar per cup:

• 1 cup of tightly packed light brown sugar weighs approximately 7 ounces or 200 grams
• 1 cup of tightly packed dark brown sugar weighs approximately 8 ounces or 225 grams

As you can see, there is a slight difference between light and dark brown sugar. The higher molasses content of dark brown sugar makes it weigh more per cup.

## Calculating the Weight of 1 2/3 Cups of Brown Sugar

Now that we know how much a single cup of packed brown sugar weighs, we can calculate the weight of 1 2/3 cups:

### For Light Brown Sugar:

• 1 cup weighs 7 oz or 200g
• 2/3 cup weighs approximately 4.67 oz or 133g (2/3 x 7 oz)
• Total for 1 2/3 cups is 7oz + 4.67oz = Approximately 11.67 ounces or 330 grams

### For Dark Brown Sugar:

• 1 cup weighs 8 oz or 225g
• 2/3 cup weighs approximately 5.33 oz or 150g (2/3 x 8 oz)
• Total for 1 2/3 cups is 8oz + 5.33oz = Approximately 13.33 ounces or 375 grams

So 1 2/3 cups of lightly packed brown sugar weighs about 11.67 ounces or 330 grams, while the same amount of tightly packed dark brown sugar weighs approximately 13.33 ounces or 375 grams.

## Volume to Weight Conversions

Here are some helpful volume to weight conversions for reference when measuring out brown sugar:

Volume Weight (Light Brown Sugar) Weight (Dark Brown Sugar)
1 tablespoon 0.5 oz / 14g 0.55 oz / 16g
1/4 cup 1.75 oz / 50g 2 oz / 55g
1/3 cup 2.33 oz / 66g 2.66 oz / 75g
1/2 cup 3.5 oz / 100g 4 oz / 110g
2/3 cup 4.67 oz / 133g 5.33 oz / 150g
3/4 cup 5.25 oz / 150g 6 oz / 170g
1 cup 7 oz / 200g 8 oz / 225g

As you can see, dark brown sugar weighs approximately 10-15% more than light brown sugar for any given volume amount. This table can help you easily convert between cups and weights when working with brown sugar in recipes.

## Does Packing Method Affect Weight?

You may be wondering if the packing method can significantly affect the weight of brown sugar. In general, there is a minor difference in weight between lightly packed versus very firmly packed brown sugar.

Here is a rough comparison:

• 1 cup lightly packed = approximately 6.5-7oz / 185-200g
• 1 cup very firmly packed = approximately 7-8oz / 200-225g

As you can see, the weight can vary by 3-4% between light and heavy packing. When a recipe specifies “packed brown sugar” it is referring to the very firmly pressed method that maximizes weight.

Most standardized volume to weight conversions and nutrition data is based on the firmly packed version. So for accuracy, always pack brown sugar into the cup tightly and level off the top when measuring.

## Tips for Packing Brown Sugar into a Measuring Cup

Packing brown sugar properly takes a bit of technique. Here are some tips:

– Use a stiff spatula or spoon to press the brown sugar down firmly into the cup. Apply pressure and pack the sugar down until it is consolidated.

– When the cup is full, run the flat edge of a knife across the top to level it off cleanly. Scrape off any excess.

– Make sure there are no air pockets or gaps inside the cup. The sugar should be compressed and uniform.

– Firmly tap the cup on the countertop to help settle and pack down the sugar further. The surface should become flat and solid.

– When done, you should not be able to pour any extra sugar into the cup without applying pressure. It will be totally packed in.

– For larger volumes like 2 or 3 cups, pack them incrementally in 1 cup portions, not all at once. This helps achieve an even tight pack.

With practice, you’ll get a feel for the difference between lightly packed and fully packed brown sugar. Remember to always pack and level it off for the most accurate measurement and recipe success.

## Weight Equivalents for Common Brown Sugar Volumes

For convenience, here are the weight equivalents for some commonly used brown sugar volume measurements:

### Light Brown Sugar

• 1/4 cup firmly packed = 1.75 ounces / 50 grams
• 1/3 cup firmly packed = 2.33 ounces / 66 grams
• 1/2 cup firmly packed = 3.5 ounces / 100 grams
• 3/4 cup firmly packed = 5.25 ounces / 150 grams
• 1 cup firmly packed = 7 ounces / 200 grams
• 1 1/4 cup firmly packed = 8.75 ounces / 250 grams
• 1 1/2 cup firmly packed = 10.5 ounces / 300 grams
• 1 3/4 cup firmly packed = 12.25 ounces / 350 grams
• 2 cups firmly packed = 14 ounces / 400 grams

### Dark Brown Sugar

• 1/4 cup firmly packed = 2 ounces / 55 grams
• 1/3 cup firmly packed = 2.66 ounces / 75 grams
• 1/2 cup firmly packed = 4 ounces / 110 grams
• 3/4 cup firmly packed = 6 ounces / 170 grams

## Weight Measurement Makes Baking Easier

While most home bakers use traditional volume measures like cups or spoons, weighing ingredients with a digital kitchen scale offers greater precision. Volume measures can vary in accuracy between packing methods, humidity, the type of cup used and other factors.

For example, tablespoons of brown sugar can clump together densely or contain more air pockets depending on the brand, affecting volume. Granulated white sugar also settles differently into a cup depending on how fine it is ground.

With a weight measure, you eliminate this variability and hassle. 100 grams of brown sugar will be exactly the same whether packed softly or firmly into a cup. Weight measures are not affected by environmental conditions or the tools used.

This makes weighing especially helpful for:

• Adapting recipes when you don’t have the exact cup measures needed
• Scaling recipes up or down – you can easily double or halve based on weight
• Ensuring consistent results and accuracy every time you bake
• Eliminating the need to level off ingredients or pack them into cups
• Allowing flexibility if you don’t have a full set of measuring cups and spoons

Many professional bakeries weigh their ingredients because it is more efficient, streamlined and precise. Gram scales are also essential for bread baking, since hydration percentages are calculated by weight.

If you want to take your home baking to the next level, consider incorporating a digital kitchen scale into your routine. They provide ease and accuracy that volume measures simply can’t match!

## Factors That Impact Brown Sugar Weight

While we’ve provided general weight conversions for packed brown sugar volumes, there are some factors that can cause the weight to vary slightly:

### Brand of Brown Sugar

– The exact proportion of molasses and moisture content can differ between brands. Some brown sugars contain a little more or less molasses or are a bit drier or softer textured. This affects density and weight.

### Altitude

– At high altitudes above 3000 feet/900 meters, brown sugar is less compact and weighs slightly less per cup than at sea level.

### Humidity & Dryness

– Brown sugar that is exposed to humidity absorbs some extra moisture and becomes softer, decreasing its weight per volume. Very dry brown sugar weighs more per cup.

### Sugar Crystal Size

– Brown sugar with slightly coarser sugar crystals weighs less than finely ground brown sugar per cup.

### Accuracy of Cups

– The actual volume capacity of different measuring cup sets varies. Standard US cups are defined as 240ml, but not all cup sets meet this exactly.

So while our weight conversions are a helpful guide, there will be some variation in practice when measuring brown sugar. For the most accuracy, always weigh brown sugar directly on a digital kitchen scale.
