Show the math
| To L | 1 cup × 0.2365882365 = 0.2365882365 L |
|---|---|
| To mL | 0.2365882365 L ÷ 0.001 = 236.5882365 mL |
What to do next
How it works
The US gallon is defined as exactly 231 cubic inches. Everything else follows from it: a quart is 1/4 gallon, a pint 1/8, a cup 1/16, a fluid ounce 1/128, a tablespoon half a fluid ounce and a teaspoon a third of a tablespoon. The converter runs every value through liters.
Things to keep in mind
These are volume units. Converting cups of flour to grams needs the density of the ingredient, because a cup of flour weighs far less than a cup of water.
