How to use this tool

Choose a conversion mode. Choose US, Metric, UK/Imperial, or Australian to set cup and spoon sizes. Select "Volume ↔ Volume" to convert measures or "Volume ↔ Weight" to convert an ingredient between volume and g, oz, lb, or kg.
Enter a value and select units. Type the amount and choose the source and target units. For volume-to-weight mode, choose an ingredient and a mass unit. The ingredient density stays fixed when you change recipe standards.
Read the result. The converted value appears instantly. Use the copy button to copy it to your clipboard.

How much is 1 cup of flour in grams?

One US cup of all-purpose flour weighs approximately 120–130 grams. The exact weight depends on how the flour is measured: spooned gently into the cup and leveled off gives about 120–125 g, while scooping directly from the bag can pack 140–150 g. This converter uses 125 g per cup (based on a density of 0.529 g/mL × 236.6 mL/cup).

For reproducible baking results, weigh flour with a kitchen scale rather than measuring by volume.

The converter lets you choose US, Metric, UK/Imperial, or Australian recipe measures. That choice changes the milliliters represented by each cup and spoon, while the selected ingredient’s density remains unchanged. You can display the mass result in grams, ounces, pounds, or kilograms.

Approximate baking weights per US cup

These reference weights use the US cup (236.588 mL) and the densities listed by this tool. The interactive calculator applies the active recipe standard, so a metric or UK/Imperial cup can produce a different weight for the same ingredient.

Measurement	Grams
1 cup all-purpose flour	≈ 125 g
1 cup bread flour	≈ 131 g
1 cup granulated sugar	≈ 200 g
1 cup brown sugar (packed)	≈ 220 g
1 cup powdered sugar	≈ 125 g
1 cup butter (softened)	≈ 215 g
1 cup butter (melted)	≈ 204 g
1 cup water / milk	≈ 237–244 g
1 cup honey	≈ 336 g
1 cup vegetable oil	≈ 216 g
1 tbsp butter	≈ 14 g
1 tsp salt	≈ 6 g
1 tsp baking powder	≈ 4.4 g

Regional cup and spoon standards

Cup and spoon sizes differ among recipe standards. Select the matching region in the converter; its reference table and unit labels update with the chosen milliliter factors.

Recipe standard	1 cup	1 tablespoon	1 teaspoon
US	236.588 mL	14.7868 mL	4.92892 mL
Metric	250 mL	15 mL	5 mL
UK/Imperial	284.131 mL	17.758 mL	5.919 mL
Australian	250 mL	20 mL	5 mL

Australian tablespoons are especially different: one is 20 mL, compared with 14.7868 mL for a US tablespoon. The fluid-ounce option is labeled as a US fluid ounce except in UK/Imperial mode, where it uses the UK imperial fluid ounce. These are volume measures; ingredient density values remain the same when you switch standards.

Frequently asked questions

How many tablespoons are in a cup?

It depends on the recipe standard. This converter uses a 236.588 mL US cup, a 250 mL metric cup, a 284.131 mL UK/Imperial cup, or a 250 mL Australian cup. An Australian tablespoon is 20 mL; the US tablespoon is 14.7868 mL.

How many grams is 1 cup of flour?

One US cup of all-purpose flour weighs approximately 125.2 g using this converter’s spoon-and-level density (0.529 g/mL × 236.588 mL). Scooping directly from the bag can pack flour to 140–150 g. Choose a recipe standard to change the cup volume; the ingredient density remains the same. Results can also be displayed in ounces, pounds, or kilograms.

How many grams is 1 cup of sugar?

One US cup of granulated white sugar weighs approximately 200 grams (0.845 g/mL × 236.6 mL). Brown sugar packed into a cup weighs about 220 g.

How many grams is 1 cup of butter?

One US cup of softened butter weighs approximately 215.5 g by density. A US butter stick is packaged as 113.5 g and is labeled as ½ US cup or 8 US tablespoons; the volume estimate is approximate and may differ from package labeling.

Why do volume-to-weight conversions differ by ingredient?

Different ingredients have different densities. Water weighs 1 g/mL, while honey (1.42 g/mL) weighs more per cup and flour (0.53 g/mL) weighs less. For precise baking, use a kitchen scale to weigh ingredients rather than measuring by volume.

Does the converter save my selected region?

Yes. The selected standard is saved only in this browser under the localStorage key toolcroft:cooking-converter:region. It stores the region name and does not send your inputs or preference to a server. Clearing this browser’s site data resets the standard to US.
