Milliliter to Cup (US) (mL to US cup)
Result
0.004226752838 Cup (US)
Formula
US cup = mL × 0.004226752838
1 mL = 0.004226752838 US cup, and 1 US cup = 236.5882365 mL.
The litre is exactly 1 dm³ (0.001 m³). The US gallon is defined as 231 cubic inches, which makes it exactly 3.785411784 L; quarts, pints, cups and fluid ounces are fixed fractions of it.
Worked examples
- 1 mL × 0.004226752838 = 0.0042267528 US cup
- 10 mL × 0.004226752838 = 0.042267528 US cup
- 100 mL × 0.004226752838 = 0.42267528 US cup
Common mistakes
- US and UK (imperial) measures share names but not sizes: the imperial gallon is 4.54609 L (20% larger), the imperial pint 568 mL and the imperial fluid ounce 28.41 mL.
- This converter uses US customary volumes. A US cup is 236.59 mL, a metric cup 250 mL, and US nutrition labels round a cup to 240 mL.
- US dry measures (dry pint, bushel) are a separate system and are not the same as liquid pints.
