Grams to Cups Butter Cooking Size Chart
This chart converts butter between grams and cups, covering 9 measurements from grams 28 up to grams 454. Because butter has a specific density that differs from other ingredients, these conversions apply only to butter — do not use them for other ingredients.
In baking and cooking, precision matters. A recipe calling for grams 28 of butter needs exactly cups 1/8 — using a conversion for a different ingredient could throw off the balance of your recipe. Our chart accounts for the actual weight-to-volume ratio of butter.

How to Measure Your Ingredients Size
For dry ingredients, spoon the ingredient into the measuring cup and level off with a straight edge — never scoop directly from the bag, as this packs the ingredient and adds up to 20% extra weight. For liquids, use a liquid measuring cup (with a pour spout) and read at eye level on a flat surface. A digital kitchen scale is the most accurate option and eliminates the need for volume conversions altogether.
Tips for Converting Butter Cooking Sizes
Weight-based measurements (grams, ounces) are more accurate than volume measurements (cups, tablespoons) for baking. Professional bakers almost always weigh ingredients.
Humidity, packing density, and grain size all affect how much of a dry ingredient fits in a cup. Two people measuring '1 cup of flour' can end up with weights differing by 30 grams.
When a recipe gives both weight and volume, always prefer the weight measurement — it is what the recipe developer used.

Frequently Asked Questions
- How do I convert butter from grams to cups?
- Use our butter conversion chart above. For example, grams 151 of butter equals cups 2/3. The chart covers 9 measurements so you can find the exact conversion you need.
- Does butter weigh the same as other ingredients per cup?
- No. Each ingredient has a different density, so 1 cup of butter weighs a different amount than 1 cup of flour, sugar, or any other ingredient. That is why ingredient-specific conversion charts like this one exist — using a generic converter will give inaccurate results.
- Should I measure butter by weight or volume?
- Weight (grams or ounces) is more accurate for baking because volume measurements like cups can vary by up to 20% depending on how the ingredient is scooped and packed. If your recipe gives both, always prefer the weight measurement. A digital kitchen scale is the most reliable tool.
- What is the smallest butter conversion in this chart?
- The smallest measurement in our chart is grams 28 of butter, which equals cups 1/8.
- What is the largest butter conversion available?
- The largest measurement covered is grams 454 of butter, which converts to cups 2. If you need a larger quantity, multiply the appropriate row from our chart.
- How do I measure butter accurately for baking?
- For cups, use the spoon-and-level method: spoon butter into the measuring cup, then sweep a straight edge across the top to level it off. Never scoop directly from the container — this packs the ingredient and gives you more than the recipe intended. For grams or ounces, use a digital scale set to zero (tared) with your bowl on it.
- Can I use this chart for butter in savoury recipes too?
- Yes. The weight-to-volume ratio of butter is the same regardless of whether you are baking or cooking a savoury dish. These conversions apply to any recipe that calls for butter.
