Cooking Measurement Converter
Convert any kitchen measure to another: teaspoons, tablespoons, fluid ounces, cups, pints, quarts, gallons, milliliters and liters for volume, and grams, ounces, pounds and kilograms for weight. Volume to volume and weight to weight need nothing else; volume to weight needs an ingredient.

1 us cups = 236.5882 milliliters

| Teaspoons | 48 |

| US fluid ounces | 8 |
| US cups | 1 |
| US pints | 0.5 |
Volumes use US customary units (US cup 236.588 mL). A metric cup is 250 mL, so recipes written in metric cups need a different base.

Formula: base = amount × size of unit; volume to weight: grams = mL × grams per mL of the ingredient.
- You entered 1 us cups (volume).
- Base amount: 1 × 236.5882 mL per unit = 236.5882 mL.
- Same kind of measure, so no ingredient density is used.
- Result: converted into milliliters = 236.5882.
Result: 1 us cups = 236.5882 milliliters
How cooking measurements convert
base = amount × size of unit
result = base ÷ size of target unit
volume to weight: grams = milliliters × grams per milliliter
Every unit here is a fixed size. Volumes are measured in milliliters and weights in grams. The calculator multiplies your amount by the size of the unit you chose, then divides by the size of the unit you want.
The US customary volumes all come from the US gallon, defined as 3.785411784 liters. A quart is a quarter of that, a pint an eighth, a cup a sixteenth (236.5882 mL), a fluid ounce a 128th (29.5735 mL), a tablespoon a 256th (14.7868 mL) and a teaspoon a 768th (4.9289 mL). So 1 cup is 8 fluid ounces, 16 tablespoons or 48 teaspoons.
Weights follow the pound, defined as exactly 0.45359237 kilograms. An ounce is one sixteenth of a pound, 28.3495 g, so 1 pound is 453.59 g.

Volume versus weight
A cup measures space, while a gram measures how much matter fills it. A cup of flour and a cup of honey take up the same room but weigh very different amounts, so no fixed number turns cups into grams. That is why this converter asks for an ingredient whenever you cross from volume to weight, and refuses to guess when you do not choose one.
The ingredient list gives approximate grams per US cup, taken from the King Arthur Baking ingredient weight chart. One cup of all-purpose flour is 120 g, granulated sugar 198 g, butter 226 g and honey 336 g. The calculator divides that weight by the 236.5882 mL in a cup to get a density in grams per milliliter.
Why ingredient weights are approximate
Powders change with handling. Flour scooped straight from the bag can weigh well over a spooned and levelled cup, and sifting makes it lighter again. Brown sugar is usually packed, while powdered sugar is measured unsifted. Brands also differ in protein, moisture and grind.
Treat any volume to weight result as a good starting point rather than a laboratory figure. For baking, weighing on a kitchen scale is more consistent than measuring by cup, which is the reason many recipes list grams.
US and metric cups
All volumes on this page use US customary sizes, so a cup is 236.588 mL. Many countries use a metric cup of 250 mL instead, about 5.7 percent larger. If your recipe uses metric cups, convert the amount to milliliters first by multiplying by 250, then enter the milliliters here.
A UK or imperial pint is 568 mL, not the 473 mL of a US pint, so check where a recipe comes from before converting pints, quarts and gallons.
Limits and rounding
The amount must be a number from 0 to 1,000,000. Results are rounded to four decimals for display only; the underlying calculation keeps full precision, so converting there and back returns your starting amount.
How to use the Cooking Measurement Converter
- Enter the amount you want to convert.
- Choose the unit you are converting from and the unit you want to convert to.
- If one is volume and the other is weight, choose the ingredient so the calculator has a density.
- Read the result and the table of related units of the same kind.
- Open Show the work to see each multiplication, or use Copy, Print or Share.
Worked example
A recipe lists 2 cups of all-purpose flour and your scale reads grams. At 120 g per cup, 2 cups is 240 g, which is 8.4658 ounces. One US cup on its own is 236.59 mL with no ingredient needed.
| Starting amount | Unit | Equals |
|---|---|---|
| 1 cup | Milliliters | 236.5882 |
| 1 cup | Fluid ounces | 8 |
| 1 cup | Tablespoons | 16 |
| 1 cup | Teaspoons | 48 |
| 1 pound | Ounces | 16 |
| 1 pound | Grams | 453.5924 |
| 2 cups all-purpose flour | Grams | 240 |
Frequently asked questions
Why do I need to pick an ingredient to convert cups to grams?
Cups measure volume and grams measure weight, and each ingredient packs a different weight into the same volume. The ingredient gives the calculator the grams per cup it needs.
How many tablespoons and teaspoons are in a US cup?
A US cup holds 16 tablespoons or 48 teaspoons. It also equals 8 US fluid ounces, half a pint and a quarter of a quart.
Is a fluid ounce the same as an ounce on a scale?
No. A fluid ounce measures volume (29.57 mL), while an ounce on a scale measures weight (28.35 g). They are close for water but differ for most other ingredients.
How accurate are the ingredient conversions?
They are approximate. Packing, sifting and brand change how much a cup weighs, so expect small differences from your own measurements and weigh baking ingredients when precision matters.
Does this tool use the US or the metric cup?
It uses the US cup of 236.588 mL. For a 250 mL metric cup, multiply the cups by 250 and enter the result in milliliters.
