Result
250 mL = 1.0567 cups (US customary)
| Unit | Amount |
|---|---|
| Cups (US customary) | 1.0567 |
| Nearest 1/8 cup | about 1 cup |
| US cups (236.59 mL) | 1.0567 |
| Metric cups (250 mL) | 1 |
| Legal cups (240 mL) | 1.0417 |
The nearest-fraction line rounds to the closest 1/8 cup. Tablespoons and teaspoons follow the chosen cup size; fluid ounces are always US fluid ounces.

Formula: milliliters = amount × mL per input unit; cups = milliliters ÷ mL per cup. US customary: 1 cup = 236.5882 mL, 1 tbsp = 14.7868 mL, 1 tsp = 4.9289 mL.
- You entered 250 mL and chose the US customary cup.
- Milliliters: 250 × 1 = 250 mL.
- Cups: 250 ÷ 236.5882 = 1.0567.
- Tablespoons: 250 ÷ 14.7868 = 16.907. Teaspoons: 250 ÷ 4.9289 = 50.721.
- Nearest 1/8 cup: 1.0567 × 8 = 8.4535, rounded to 8 eighths = 1.
Result: 250 mL = 1.0567 cups (US customary)
How milliliters convert to cups
cups = milliliters ÷ mL per cup
US cup = 236.5882365 mL, metric cup = 250 mL, US legal cup = 240 mL
A cup is a fixed volume in milliliters, so the conversion is a single division. The calculator first turns your amount into milliliters (1 liter is 1,000 mL and 1 US fluid ounce is 29.5735 mL), then divides by the size of the cup you chose.
Three cup sizes are in everyday use. The US customary cup is exactly 236.5882365 mL, which follows from the US gallon of 3.785411784 liters and 16 cups to the gallon. The metric cup used in Australia, New Zealand, Canada and many cookbooks is a round 250 mL. The US legal cup, used on nutrition labels, is rounded to 240 mL.
The difference matters more than it looks. 250 mL is 1.0567 US cups but exactly 1 metric cup and 1.0417 legal cups. Tablespoons and teaspoons follow the same choice: the US tablespoon is 14.79 mL, while the metric and label tablespoons are 15 mL.

Which cup size should you choose?
Use the cup size of the recipe, not of your kitchen. An American recipe written in US cups should be converted with the US customary option. A recipe from a metric country, where a cup is 250 mL, should use the metric option. Packaged food labels in the United States state a cup as 240 mL, so choose US legal when you read a nutrition panel.
If you are unsure, the three sizes differ by less than 6 percent. That suits soup or a smoothie, but baking is less forgiving, so use one size for the whole recipe.
The nearest 1/8 cup
Measuring cups come in fractions, not in four-decimal numbers, so the calculator also shows the nearest eighth of a cup for the size you picked. 350 mL is 1.4794 US cups, which rounds to 1 1/2 cups.
The line says "about" whenever the amount is not exactly on an eighth step. Rounding to 1/8 cup can be off by up to 1/16 cup, roughly 15 mL, so for small amounts switch to the tablespoon and teaspoon rows, which are more precise.
Common milliliter amounts in cups
The table in the worked example lists the amounts cooks look up most. A 500 mL bottle of milk is just over 2 US cups. A 1 liter carton is about 4 1/4 US cups, or exactly 4 metric cups. A 750 mL wine bottle is a little over 3 US cups.
Half a US cup is 118.29 mL, and half a metric cup is 125 mL.
Edge cases and limits
The amount must be a finite number above 0 and at most 1,000,000 in the unit you choose. Very small amounts are accepted, but anything under 1/16 cup shows as "less than 1/8".
Results are rounded to four decimals for display only. This page converts volume, not weight. A cup of flour and a cup of honey have the same volume but very different grams, so use Grams to Cups for ingredient weights.

Worked example
A recipe lists 350 mL of stock. In US customary cups that is 350 ÷ 236.5882365 = 1.4794 cups, which rounds to 1 1/2 cups. It is also 23.6698 tablespoons or 11.8349 US fluid ounces. In metric cups it is exactly 1.4 and in legal cups 1.4583.
