Converting us cup to milliliter comes up frequently in cooking, chemistry, medicine, and engineering. A recipe written in metric units may need to be adapted for a kitchen using milliliter, or a laboratory protocol may specify volumes in us cup that need to be measured with equipment calibrated in milliliter.
In everyday use, knowing that 5 cup = 1183 mL and 10 cup = 2366 mL covers most common situations. For bulk calculations, 100 cup = 2.366e+04 mL is a useful anchor. The reverse conversion — milliliter back to us cup — uses the factor 0.004227, so 1 mL = 0.004227 cup.
All conversions use the internationally recognized factor of exactly 1 cup = 236.6 mL. 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: Milliliter = US Cup × 236.588
Multiply any us cup value by 236.588 to get milliliter. One us cup equals 236.588 mL.
Reverse: US Cup = Milliliter × 0.0042267571
Cups × 236.6 = mL. Use × 240 for quick estimates.
Round to 240 mL per cup — only 0.6% error.
½ cup = 120 mL, ¼ cup = 60 mL.
Follows American recipes using cups for flour, sugar, milk, and butter.
Tests and standardizes recipes in cup measurements before international publication.
Uses cup portions as standardized serving-size references for dietary counseling.
Teaches beginner cooks using cups as intuitive, equipment-free measuring tools.
Converts cup-based recipes to liter or kilogram quantities for industrial production.
Converts US cup measurements to metric mL when cooking American recipes abroad.
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.
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.
