Converting milliliter to us cup comes up frequently in cooking, chemistry, medicine, and engineering. A recipe written in metric units may need to be adapted for a kitchen using us cup, or a laboratory protocol may specify volumes in milliliter that need to be measured with equipment calibrated in us cup.
In everyday use, knowing that 5 mL = 0.02113 cup and 10 mL = 0.04227 cup covers most common situations. For bulk calculations, 100 mL = 0.4227 cup is a useful anchor. The reverse conversion — us cup back to milliliter — uses the factor 236.6, so 1 cup = 236.6 mL.
All conversions use the internationally recognized factor of exactly 1 mL = 0.004227 cup. Calculations are performed in IEEE 754 double-precision floating point, giving accuracy to at least 8 significant figures — more than sufficient for any practical application.
Formula: US Cup = Milliliter × 0.0042267571
Multiply any milliliter value by 0.0042267571 to get us cup. One milliliter equals 0.0042267571 cup.
Reverse: Milliliter = US Cup × 236.588
mL ÷ 237 = cups. Round to ÷ 240 for easier mental math (1.3% high).
Use 240 mL per cup in your head — only 1.4% off.
120 mL = ½ cup, 60 mL = ¼ cup, 30 mL = ⅛ cup.
Measures liquid medication doses, compound quantities, and vial volumes in milliliters for precise dispensing.
Scales extracts, food colorings, and liquid flavorings in mL for consistent batch replication.
Pipettes reagents, prepares serial dilutions, and calibrates instruments using mL graduations.
Calculates weight-based medication doses converted to mL for syringe administration.
Blends fragrance accords in small mL batches with high precision and high ingredient costs.
Develops skincare products in 50-500 mL batches before scaling to full production.
The milliliter is one-thousandth of a liter, in use since the metric system was codified in France in 1795. The milli- prefix (from Latin mille, thousand) was standardized as part of the original SI prefix system.
Milliliters are the workhorse of medicine and cooking: syringes, dropper bottles, and nutritional labels all rely on mL for precise small-volume measurement. A standard US teaspoon is approximately 4.929 mL.
Interesting fact: The milliliter is numerically identical to the cubic centimeter (cm³), so 1 mL = 1 cm³ exactly. This equivalence is widely used in medicine, where a 5 cc syringe holds exactly 5 mL.
The US customary cup is defined as exactly 8 US fluid ounces, or 236.588 mL. It was standardized by Fannie Farmer in her 1896 cookbook The Boston Cooking-School Cook Book.
The cup is the backbone of US baking: nearly every American recipe uses cup measurements for flour, sugar, butter, and liquids. Standard sets include 1 cup, ½ cup, ⅓ cup, and ¼ cup.
Interesting fact: Australia uses a metric cup of 250 mL, slightly larger than the US cup, which can cause recipe confusion in international cooking.
