Butter mL to grams conversion chart
These values use the clearly stated baseline of 0.96 g/mL. For a recipe that specifies grams, weighing is still more reliable than estimating the mass of a packed cup.
| Volume | Estimated mass | US cups (volume) |
|---|---|---|
| 1 mL | 0.96 g | 0.004 US cups |
| 5 mL | 4.8 g | 0.021 US cups |
| 10 mL | 9.6 g | 0.042 US cups |
| 15 mL | 14.4 g | 0.063 US cups |
| 25 mL | 24 g | 0.106 US cups |
| 30 mL | 28.8 g | 0.127 US cups |
| 50 mL | 48 g | 0.211 US cups |
| 60 mL | 57.6 g | 0.254 US cups |
| 75 mL | 72 g | 0.317 US cups |
| 100 mL | 96 g | 0.423 US cups |
| 125 mL | 120 g | 0.528 US cups |
| 150 mL | 144 g | 0.634 US cups |
| 180 mL | 172.8 g | 0.761 US cups |

The final column shows the volume expressed as cups, not the weight of a universal “cup of butter.”
How to turn mL of butter into grams
Volume tells you how much space soft butter takes. Mass tells you how much of the ingredient is present. You connect the two through bulk density, normally written as grams per milliliter (g/mL).
250 mL
0.96 g/mL
240 g
The forward formula is grams = mL × density (g/mL). The inverse is mL = grams ÷ density (g/mL). Keep the same density on the way back; mixing figures from different ingredient types defeats the comparison.
Check the exact form
Identify whether your ingredient is soft butter or a different form. A substitution between forms can change volume and texture.
Choose a defensible factor
Start with the site reference of 0.96 g/mL, or use the weight-per-cup printed by your ingredient manufacturer.
Calculate mass
Multiply the measured mL by 0.96 for this reference. For example, 250 mL gives about 240 g.
Verify and round
Check the recipe’s specified measuring method, then use a scale when accuracy matters. Round to a sensible number of grams.
Different forms of butter do not weigh the same
Do not melt butter merely to measure it for a recipe that needs softened butter; the texture affects dough and batter. This side-by-side table mixes the site's disclosed estimates with explicit published cup-weight references. The reference notes prevent figures calculated under different measuring methods from being mistaken for an interchangeable standard.
| Variety or method | Reference g/mL | 100 mL | 250 mL |
|---|---|---|---|
| Soft butter, site estimate | 0.96 | 96 g | 240 g |
| Melted butter, site estimate | 0.91 | 91 g | 227.5 g |
| King Arthur butter reference | 0.955 | 95.52 g | 238.81 g |
| Ghee, melted estimate | 0.91 | 91 g | 227.5 g |
- Soft butter, site estimate: The measure is filled without large gaps
- Melted butter, site estimate: Use a liquid measuring vessel
- King Arthur butter reference: 113 g for 1/2 US cup, from weight chart
- Ghee, melted estimate: Clarified fat; not identical to butter
Teaspoons, tablespoons and cups for {escape(name.lower())}
One metric cup equals 250 mL, while a US customary cup is about 236.59 mL. A metric teaspoon is commonly treated as 5 mL and a metric tablespoon as 15 mL. Do not silently replace a national measuring convention with another.
{spoon}{escape(heading)}
Useful conversions usually start with a practical question: whether a recipe gives only volume, whether a product's form differs, and whether precision matters to the final result.
{distinct}How to measure {escape(name.lower())} more consistently
{tips}For each variation, document whether you used a leveled measure, packed cup or a pre-weighed quantity. This makes comparisons reproducible across batches.
Soft butter, melted butter and whipped butter
Solid butter retains a shape; softened butter can be spread or pressed into a measure; melted butter flows into the available volume. These states differ in how much air or empty space can be present. Mass, however, does not disappear just because butter is melted. If you melt an intact 100 g portion without losses, it still weighs about 100 g.
Marked butter sticks can be convenient when the product follows a known size standard. The King Arthur chart gives approximately 113 g for a half US cup of butter. Using the ordinary US cup definition gives about 0.955 g/mL on that measuring basis, close to the illustrative 0.96 g/mL soft-butter preset. A melted-butter estimate of 0.91 g/mL is a different preparation reference.
Whipping introduces air, so a cup of whipped butter is not a sensible substitute for a cup of unwhipped butter in a weighed formula. Follow the recipe’s requested state rather than choosing whichever preparation is easiest to spoon into a cup.
For pastries in particular, butter temperature affects layering and texture. Converting units cannot compensate for changing cold butter to melted butter.
Grams to milliliters of {escape(name.lower())}
Going backwards needs the same density assumption. For example, a 100 g amount of {escape(kind)} occupies about {smart_fmt(100/d,2)} mL at {d} g/mL. It is not a statement that all forms of the ingredient take the same amount of space.
{reverse}Worked recipe: cookies that require softened butter
Consider a recipe that asks for 125 mL of softened butter. At the illustrative soft-butter density of 0.96 g/mL, that is about 120 g. This is not permission to melt the butter and pour exactly 125 mL of liquid. Creaming softened butter with sugar forms small air pockets that influence cookie texture; melting removes that mechanical structure.
If the recipe already supplies 120 g, weighing it is more dependable than pressing soft butter into a container. Set the butter on a tared bowl and measure directly. Let it soften as directed only after the mass is set. The conversion controls quantity, while the method controls how that quantity behaves.
Worked recipe: pouring melted butter into batter
A recipe may instead ask for 150 mL melted butter. Using the site's 0.91 g/mL liquid estimate gives about 136.5 g. This is different from the softened-butter estimate because each is a practical model for a different physical form and measuring process. Melted fat may also remain inside a measuring cup, so transferring the entire weighed amount is important when the ratio of ingredients is sensitive.
If you know your specific product's package weight, weigh out the required butter first and melt it in a small vessel. That avoids the challenge of bringing a warm liquid precisely to a line while minimizing losses from pouring.
Worked recipe: converting butter marked in tablespoons
A common US butter package labels a stick by tablespoons and total weight. A half US cup corresponds to eight US tablespoons, and a King Arthur reference places that half-cup quantity at around 113 g. That can be helpful for translating a US recipe to grams, but the package's own weight marking should be the primary reference if it is printed.
Metric teaspoons and tablespoons also have their own standards. A recipe from Australia may define a tablespoon as 20 mL rather than the 15 mL metric culinary spoon used elsewhere. Mixing tablespoon definitions may produce a larger percentage difference than choosing between two butter-density estimates.
How butter conversions affect substitutions
Butter contains water, milk solids and fat. It is not equivalent to an equal mass of clarified ghee or an equal volume of vegetable oil in every recipe. Even where two fats have similar density, the moisture content can change a cake or pastry. A calculator can convert units, but it cannot determine whether the ingredient substitution preserves flavor, emulsification or dough structure.
Follow the original temperature and ingredient-state instructions. Use grams for precision, use volume conversions as a documented fallback, and avoid treating a unit conversion as a complete recipe reformulation.
Questions about {escape(name.lower())} conversion
How many grams are in 100 mL of butter?
Using the stated 0.96 g/mL reference, 100 mL is approximately 96 g. Check the ingredient form and measuring method.
How much is 250 mL of butter?
At 0.96 g/mL, 250 mL is around 240 g. A metric cup is 250 mL; a US customary cup is smaller.
How many mL are in 100 g of butter?
Divide 100 by 0.96. The result is about 104.2 mL, assuming the same bulk density.
Is 1 mL the same as 1 gram?
Not for every food. One milliliter of butter has an estimated mass of 0.96 g in the stated reference; 1 g/mL is an approximation for water.
Why does another butter conversion chart give a different number?
Different brands, forms, temperatures, packing techniques and cup definitions can produce different apparent densities. Do not melt butter merely to measure it for a recipe that needs softened butter; the texture affects dough and batter.
Should I use a kitchen scale or measuring cup?
A scale measures ingredient mass directly and is generally preferable where a recipe lists grams. A calibrated cup is useful for liquids or rough portions.
