How it works
Use the formula ml = cup × 240 to convert any value. Quickly convert cups (cup) to milliliters (ml) with precise results, formula, and a quick reference table.
Real-world use cases
Where cups to milliliters conversion actually matters in day-to-day life and work.
International recipes mix cups, tablespoons, milliliters, and fluid ounces — the same word can mean different amounts.
European pumps dispense liters; US pumps dispense gallons. Converting helps compare fuel economy honestly.
Tank capacity, brewing batches, and chemical dosing all rely on accurate volume conversion.
Watering rates, fertilizer mixing, and rainwater storage planning.
Washing machine drums, kettles, and water tanks are sized in liters or gallons depending on the market.

Understanding the units
Volume measures how much three-dimensional space something occupies. The catch with volume is that 'gallon', 'pint', and 'cup' mean different amounts in the US and the UK.
- Liter (L)
- Metric unit equal to 1,000 cm³ — the volume of a 10×10×10 cm cube. Universal in most of the world.
- US gallon
- 3.78541 L. Used in the US for fuel, milk, and large beverages.
- UK (imperial) gallon
- 4.54609 L — about 20% larger than the US gallon. Still used informally in the UK and in some Commonwealth countries.
- Fluid ounce
- Two definitions: US fl oz ≈ 29.57 mL, UK fl oz ≈ 28.41 mL. Check the source before converting.
Common mistakes
- US vs UK gallons
A 'gallon' in a British recipe is 20% larger than a US gallon. Using the wrong one wrecks fuel-economy comparisons and recipes alike.
- Mixing fluid ounces and ounces
Fluid ounces measure volume, ounces measure weight. They only coincide for water and a few other liquids.
- Cup size varies
A US cup is 240 mL, a metric cup is 250 mL, a UK cup is about 284 mL. Recipe outcomes depend on which one you used.
When precision matters
Situations where an accurate cups to milliliters conversion is more than a nice-to-have.
- Pharmacy and medicine
Liquid medication is dosed in milliliters; a misread fluid ounce can mean a 30× overdose.
- Brewing and fermentation
Yeast and hop ratios depend on exact wort volume; small errors change flavor and alcohol content.
- Industrial chemicals
Mixing ratios for concrete, paint, and cleaners need accurate volumes to perform as advertised.
Metric vs imperial
Liters are standard almost everywhere. The US sticks to gallons, quarts, pints, and cups for everyday volumes. The UK officially uses liters but pubs still pour pints and milk sometimes comes in pints.
History and context
The liter was introduced with the metric system in 1795 and standardized to exactly 1 cubic decimeter in 1964. The gallon descends from medieval English wine and ale measures; the US adopted the older 'wine gallon' (3.785 L) while the UK reformed to the larger imperial gallon (4.546 L) in 1824.
Trust and accuracy
- •Every formula is reviewed against authoritative references (NIST, BIPM, and unit-definition standards).
- •Calculations run client-side using exact conversion factors — no rounded shortcuts.
- •Where a quantity depends on context (temperature scale, gallon definition, fuel type), the page explains which convention is used.
- •Results are estimates wherever real-world variation applies. For medical, legal, financial, or engineering decisions, verify with a qualified source.
