Cup measurements are familiar but notoriously inconsistent. The same cup measure can hold 15% more or less of an ingredient depending on how you fill it. That's why 1 cups to grams isn't one fixed number — and why professional kitchens have moved to grams as the standard.
This page converts 1 cup into precise gram weights for 22 common ingredients, using density values that match the King Arthur Baking, Bob's Red Mill, and USDA reference standards. The conversion formula is simple: grams = 1 × density of the ingredient (in grams per cup).
Why 1 Cup Equals Different Gram Amounts
The reason 1 cup of flour weighs differently than 1 cup of sugar comes down to density — how tightly packed an ingredient's particles are inside a given volume. Flour is full of air and has a fluffy structure, so a cup holds relatively few grams. Sugar crystals are heavier and pack closer together, so the same cup volume holds significantly more weight.

1 Cup in Milliliters, Tablespoons & Other Units
Cups are a US-specific measurement. If you're working from a recipe that uses milliliters, fluid ounces, or metric cups, here's how 1 US cup converts to other volume and weight units:
| Unit | 1 Cup = | Notes |
|---|---|---|
| Milliliters | 237 mL | 1 US cup = 236.59 mL |
| Liters | 0.237 L | For larger batches |
| Tablespoons | 16.0 tbsp | 1 cup = 16 tbsp |
| Teaspoons | 48.0 tsp | 1 cup = 48 tsp |
| Fluid ounces (US) | 8.00 fl oz | 1 cup = 8 fl oz |
| Pints (US) | 0.500 pt | 1 cup = ½ pint |
| Quarts (US) | 0.250 qt | 1 cup = ¼ quart |
| Gallons (US) | 0.062 gal | 1 cup = 1/16 gallon |
| Metric cups (250 mL) | 0.946 metric cups | Australia, NZ |
| UK cups (284 mL) | 0.833 UK cups | Imperial standard |
| Ounces (water, weight) | 8.35 oz | For water/milk only |
| Pounds (water, weight) | 0.522 lb | For water/milk only |
| Kilograms (water, weight) | 0.237 kg | For water/milk only |
Why Bakers Convert 1 Cup to Grams Instead of Measuring by Volume
The shift toward grams in baking isn't an accident, the answer is consistency. Even the most careful home cook can pack a cup of flour 10–30% denser than another batch — and that variation makes the difference between a tender crumb and a tough one.
A widely cited King Arthur Baking study found that the same recipe could yield wildly different results based on how the flour cup was filled: spooned-and-leveled gave around 120–125 g, while scoop-and-shake gave 150–160 g. That's a 25% swing in your most important ingredient — enough to change a bread's hydration percentage entirely.
Grams remove this ambiguity. 1 cup of all-purpose flour is always 125 grams — no matter who's measuring, no matter how humid the kitchen is, no matter how compacted the bag has become in the pantry. That's why scale-based baking has become the gold standard in professional kitchens worldwide.

- Defined as exactly 250 mL. Standard in Australia, New Zealand, and Latin America. About 5.6% larger than a US customary cup.
- UK / Imperial Cup
- Defined as 284.131 mL (10 imperial fluid ounces). Rarely used in modern UK recipes, which favor grams and milliliters.
- Gram
- A metric unit of mass equal to 1/1000 of a kilogram. The internationally recognized standard for weighing food ingredients.
- Density
- Mass per unit volume, expressed here as grams per cup. The figure that turns a volume measurement into a weight measurement.
1 Cups to Grams — Frequently Asked Questions
How many grams is 1 cup?
It depends on what you're measuring. 1 cup of water is about 237 grams, but 1 cup of all-purpose flour is only about 125 grams. Granulated sugar lands in between at 200 grams. The exact gram weight depends on the ingredient's density.
Is 1 cup of flour the same as 1 cup of sugar in grams?
No. 1 cup of flour weighs about 125 grams, while 1 cup of granulated sugar weighs about 200 grams — roughly 60% more. Sugar is denser than flour, so the same volume holds more weight.
How do I convert 1 cups to grams?
Multiply 1 by the ingredient's density in grams per cup. For example, all-purpose flour is 125 g/cup, so 1 × 125 = 125 grams. Use the calculator at the top of this page for any of 80+ ingredients.
Should I use a kitchen scale instead of measuring cups?
For baking, yes. A digital scale is the single biggest accuracy upgrade you can make in the kitchen. Scales cost about $15 and eliminate the 10–30% variation that comes from how you fill a measuring cup.
How do I convert 1 cup of something not in your table?
Use the calculator at the top of the page — it includes 80+ ingredients across liquids, flours, sugars, fats, grains, nuts, and baking essentials. If your ingredient still isn't listed, look up its density (grams per cup) and multiply by 1.
Are these US cups or metric cups?
All conversions on this page use the US customary cup (236.59 mL). 1 US cup equals 0.946 metric cups (250 mL each) or 0.833 UK imperial cups (284.13 mL each). For Australian, British, or European recipes, factor in that small difference.
Can I convert 1 cup to grams for any liquid the same way?
Almost. Water, milk, and most thin liquids are very close in density (236–240 g/cup). Oils are lighter (around 218 g/cup). Honey, maple syrup, and corn syrup are much heavier (320–340 g/cup) because of dissolved sugars. Always check the specific liquid.
