How many grams of butter is 1 2 cup?

Quick Answer

1/2 cup of butter equals 115 grams. This is based on the standard measurement that 1 cup of butter equals 227 grams. Since 1/2 cup is half of 1 cup, 1/2 cup contains half as many grams of butter, which equals 115 grams.

Detailed Answer

Determining how many grams are in 1/2 cup of butter requires knowing two key pieces of information:

  • The standard conversion between cups and grams for butter
  • The relationship between 1/2 cup and 1 cup

Let’s look at each of these in turn:

Standard Butter Conversion

For most ingredients, 1 cup equals 240 grams. However, the conversion for butter is different. According to the United States Department of Agriculture (USDA) guidelines, the following standard measurement applies to butter:

  • 1 cup butter = 227 grams

So if you need to convert butter amounts between cups and grams, you should use the ratio of 1 cup equals 227 grams, not the normal 1 cup = 240 grams conversion. This is important to keep in mind any time you are measuring butter for a recipe.

Relationship Between 1/2 Cup and 1 Cup

Now that we know 1 cup of butter equals 227 grams, the next step is applying this conversion to a 1/2 cup amount. A 1/2 cup is simply half the volume of a full cup. So it will contain half the number of grams as a full cup amount.

To calculate half of 227 grams, we divide 227 by 2:

  • 227 grams (1 cup butter) / 2 = 113.5 grams

For simplicity’s sake, this is usually rounded up to 115 grams. So the final standard conversion is:

1/2 cup butter = 115 grams

To summarize:

  • 1 cup butter = 227 grams (per USDA guidelines)
  • 1/2 cup is half of 1 cup
  • Half of 227 grams is 113.5 grams
  • When rounded up, this equals 115 grams

Visualizing the Conversion

To provide a helpful visualization comparing 1/2 cup and 1 cup butter amounts in both volume and weight, here is a table showing the standard conversions:

Butter Amount Volume (Cups) Weight (Grams)
1/2 cup 1/2 cup 115 grams
1 cup 1 cup 227 grams

As the table shows, while a 1/2 cup measure of butter is half the volume of a full cup, it weighs only about half as much in grams. This highlights why measuring butter by weight instead of volume is often recommended for maximum accuracy in recipes.

When Precision Matters

There are some instances when precision is especially important in measuring butter. For example:

  • Baking – When following delicate baking recipes, every gram of butter can make a difference.
  • Portioning – If you need to divide butter into perfectly equal portions by weight, grams will be much more precise than cups.
  • Calorie counting – Knowing exact gram amounts will give you the best nutrition info for tracking calories and fat.

For these situations, it’s best to use a kitchen scale to weigh butter directly in grams for the most accuracy.

But for most general cooking and baking needs, the standard 1/2 cup = 115 gram butter conversion will provide enough precision. Even typical kitchen measuring cups designed for portioning butter have some margin of error between 112-118 grams when filled to the 1/2 cup line. So the 115 gram estimate works well for most purposes.

Metric Conversions

In countries outside the United States, recipes may call for butter amounts by weight in grams rather than imperial cup measurements. For reference, some of the most common metric conversions are:

Butter Amount Grams
125 g 4.4 ounces
250 g 8.8 ounces (1/2 pound)
500 g 1 pound

So if you are following a European recipe, you may see butter quantities like 125 g or 250 g rather than volumes like 1/2 cup or 1 cup. Now you know that 125 g is very close to a 1/2 cup amount of butter, since it equals about 4.4 ounces vs 4 ounces in a 1/2 cup. This can help you adapt recipes between metric and imperial units.

Tips for Measuring Butter

Whether you are measuring butter by volume or weight, here are some tips for accuracy:

  • Use standard butter sticks – The wrappers are marked with tablespoon divisions for easy portioning. Regular sticks also weigh 4 ounces or 1/2 cup.
  • Cut straight across – Slice the butter lengthwise for neat, even portions.
  • Pack it tightly – When using measuring cups, pack the butter down firmly to fill air pockets.
  • Level it off – Scrape off excess butter with a straight edge like a butter knife. Don’t leave rounded tops.
  • Use proper tools – Butter paddles or scrapers make portioning easier.
  • Check your scale – Make sure your kitchen scale is calibrated properly and tarred before weighing.
  • Chill it first – Butter is easier to cut and shape when well chilled.

Following these tips will remove some of the hassle and mess when measuring those buttery baked goods and dishes.

Common Butter Portions

Knowing the grams for common butter measurements can simplify recipe conversions and adjustments. Here are some of the most frequently used portions:

Butter Portion Conversion to Grams
1 tablespoon 14 grams
2 tablespoons (1/4 stick) 28 grams
1/4 cup (1/2 stick) 57 grams
1/3 cup (2/3 stick) 76 grams
1/2 cup (1 stick) 115 grams

You can reference this handy gram conversion chart any time you need to make substitutions in recipes that call for odd butter amounts like 3 tablespoons or 1/3 cup.

The Role of Fat Content

One factor that can affect the gram weight of butter is its fat percentage. Standard butter contains at least 80% milkfat. However, you can also purchase butter with reduced fat content:

  • Light butter: 40-60% milkfat
  • Reduced-fat butter: 60-70% milkfat
  • Low-fat butter: 40% milkfat

Butter with less total fat will be lighter in weight and contain fewer calories per cup in comparison to full-fat butter:

Butter Type Grams/Cup Calories/Cup
Regular butter 227 grams 814 calories
Light butter 189 grams 576 calories
Low-fat butter 135 grams 492 calories

So if you substitute reduced-fat or light butters in a recipe, you need to account for differences in both gram weight and calorie levels compared to regular full butter.

Stick Butter vs. Spreadable Butter

The texture of butter can also impact its density and gram weight. Traditional stick butter is made to be dense and firm enough to retain its shape at room temperature. Butter that is whipped or blended with oil to make it spreadable has more air mixed in, so it may weigh less per cup than regular butter sticks.

Be aware that using lighter, whipped butter may alter the texture and richness of baked goods compared to recipes made with regular butter sticks. The difference is relatively small, but can matter in certain delicate recipes.

Salted vs. Unsalted Butter

Salted and unsalted butter contain minimal differences in weight and gram content. Adding a small amount of salt does not materially affect the density or nutrition profile.

Typically, salted butter simply has up to 1/4 teaspoon of salt per 1/2 cup blended in. This equals about 400 milligrams of added sodium. So if using salted instead of unsalted butter, you may need to reduce added salt in a recipe slightly. But the gram weight will be the same.

Butter Substitutes

There are many non-dairy products available that can be used in place of butter, including:

  • Margarine
  • Plant-based spreads
  • Oil blends
  • Shortenings

These butter substitutes can vary widely in their cup-to-gram conversions compared to the standard 1/2 cup = 115 grams for real dairy butter.

For example, a trans-fat free margarine might weigh only 90 grams per 1/2 cup. Oils and shortening can range from 108-120 grams. Be sure to check labels for product-specific weights to determine the right gram amounts to use in recipes. Proper substitutions are key for the best results.

Ghee as an Alternative

One butter alternative growing in popularity is ghee. Ghee is clarified butter that has the milk solids removed. It provides a higher smoke point than regular butter, but a similar nutty flavor.

Ghee weighs only 100 grams per 1/2 cup compared to 115 grams for an equivalent butter amount. Adjusting recipes to account for the slightly lower gram weight of ghee versus regular butter can prevent issues with moisture, texture, and richness when substituting.

Converting Butter Volume to Grams

When working with any butter recipe, it helps to know some simple formulas for converting the volumes to gram weights:

  • 1/4 cup butter = 57 grams
  • 1/3 cup butter = 76 grams
  • 1/2 cup butter = 115 grams
  • 2/3 cup butter = 152 grams
  • 3/4 cup butter = 170 grams
  • 1 cup butter = 227 grams

Using these quick conversions, you can adjust any butter amount from cups to grams. This allows you to more precisely calibrate recipes and measurements.
