US cups conversion reference
US cups to Milliliters
One us cups is 236.588237 milliliters, and one milliliters is 0.004227 us cups.
A milliliter is one thousandth of a liter, and exactly the same volume as one cubic centimeter. It is used for drinks, medicine doses and recipe quantities.
- 1 cup= 236.588237 mL
- 2 cup= 473.176473 mL
- 5 cup= 1,182.941183 mL
A milliliter is one thousandth of a liter, exactly one cubic centimeter, or 0.000001 cubic meters. It is the small metric unit for liquid and dose volumes.
Medicine doses, laboratory samples, cosmetics, flavorings and small bottles of liquid are measured in milliliters. Syringes, measuring spoons and dosing cups are graduated in milliliters. Beverage cans and bottles often carry the volume on the label.
US cups to Liters
One us cups is 0.236588 liters, and one liters is 4.226753 us cups.
A liter is one thousandth of a cubic meter. It is the everyday metric unit for liquids — bottled water, fuel, milk and cooking oil.
- 1 cup= 0.236588 L
- 2 cup= 0.473176 L
- 5 cup= 1.182941 L
The liter is exactly one cubic decimeter, or 0.001 cubic meters, and it equals 1,000 milliliters. It is accepted for use with the International System as a named unit of volume.
Fuel, bottled water, cooking oil, paint, milk and engine coolant are sold in liters in most countries, and vehicles quote fuel use in liters per 100 kilometers. Recipes use the unit as well.
US cups to Cubic meters
One us cups is 2.3659e-4 cubic meters, and one cubic meters is 4,226.752838 us cups.
A cubic meter is 1,000 liters, and the volume of a cube one meter on each side. It is used for bulk water, concrete and sand, and for shipping volume.
- 1 cup= 2.3659e-4 m³
- 2 cup= 4.7318e-4 m³
- 5 cup= 0.001183 m³
The cubic meter is the International System unit of volume, the space in a cube with one-meter edges, exactly 1,000 liters or one kiloliter. It is the reference volume against which metric liquid and bulk measurements are defined.
Concrete, water consumption, natural gas, soil, shipping volumes and reservoir capacity are recorded in cubic meters. Utility bills in metric countries often express water and gas use this way.
US cups to Cubic centimeters
One us cups is 236.588237 cubic centimeters, and one cubic centimeters is 0.004227 us cups.
A cubic centimeter equals one milliliter exactly. It is used for engine displacement, medicine doses and small solid volumes — a 1,500 cc engine displaces 1,500 of them.
- 1 cup= 236.588237 cm³
- 2 cup= 473.176473 cm³
- 5 cup= 1,182.941183 cm³
US cups to Cubic inches
One us cups is 14.4375 cubic inches, and one cubic inches is 0.069264 us cups.
A cubic inch is 16.387064 milliliters. It is used for engine displacement in the United States and for small volumes in imperial engineering.
- 1 cup= 14.4375 in³
- 2 cup= 28.875 in³
- 5 cup= 72.1875 in³
US cups to Cubic feet
One us cups is 0.008355 cubic feet, and one cubic feet is 119.688312 us cups.
A cubic foot is 28.316846592 liters, and the volume of a cube one foot on each side. It is used for gas meters, freight and the capacity of appliances and containers.
- 1 cup= 0.008355 ft³
- 2 cup= 0.01671 ft³
- 5 cup= 0.041775 ft³
A cubic foot is the volume of a cube with edges one foot long, exactly 28.316846592 liters or 0.028316846592 cubic meters. It is a unit of volume, not of area.
Shipping containers, natural gas, water supply, refrigeration and timber are measured in cubic feet in the United States and parts of the freight trade. Appliance capacities also use it.
US cups to US gallons
One us cups is 0.0625 us gallons, and one us gallons is 16 us cups.
A US gallon is 3.785411784 liters, defined as 231 cubic inches. It is the standard liquid and fuel unit in the United States, and is about 20% smaller than an imperial gallon.
- 1 cup= 0.0625 gal
- 2 cup= 0.125 gal
- 5 cup= 0.3125 gal
A US gallon is exactly 3.785411784 liters, or 231 cubic inches, and it divides into four quarts, eight pints or 128 US fluid ounces. It is a defined liquid volume and not a unit of mass.
Fuel at filling stations, paint, milk, water and agricultural sprays are sold by the US gallon in the United States and in some export markets. Larger tanks and drums are also rated in gallons.
US cups to US quarts
One us cups is 0.25 us quarts, and one us quarts is 4 us cups.
A US quart is a quarter of a US gallon, or 0.946352946 liters. It is used for milk, oil and other liquids in the United States.
- 1 cup= 0.25 qt
- 2 cup= 0.5 qt
- 5 cup= 1.25 qt
US cups to US pints
One us cups is 0.5 us pints, and one us pints is 2 us cups.
A US pint is half a US quart, or 0.473176473 liters. A UK or imperial pint is larger, at 0.56826125 liters, which is why the same drink measures differently in each country.
- 1 cup= 0.5 pt
- 2 cup= 1 pt
- 5 cup= 2.5 pt
US cups to US fluid ounces
One us cups is 8 us fluid ounces, and one us fluid ounces is 0.125 us cups.
A US fluid ounce is 29.5735295625 milliliters, one sixteenth of a US pint. It is used for drinks, spirits and recipe measures in the United States.
- 1 cup= 8 fl oz
- 2 cup= 16 fl oz
- 5 cup= 40 fl oz
A US fluid ounce is exactly 29.5735295625 milliliters, one 128th of a US gallon. It measures liquid volume and is not the same as the ounce of mass.
Beverage bottles, cocktail recipes, medicine cups, infant formula and cosmetic containers are labelled in US fluid ounces in the United States, and bar measures follow the same unit.
US cups to Imperial gallons
One us cups is 0.052042 imperial gallons, and one imperial gallons is 19.215199 us cups.
An imperial gallon is 4.54609 liters, about 20% more than a US gallon. It is the traditional UK and Commonwealth liquid unit, now largely replaced by liters.
- 1 cup= 0.052042 imp gal
- 2 cup= 0.104084 imp gal
- 5 cup= 0.260211 imp gal
What us cups are used for
A US cup is 236.5882365 milliliters, or 8 US fluid ounces. It is the standard measure in American recipes; metric and Australian cups are 250 milliliters, so a recipe's cup depends on where it was written.
A US cup is exactly 236.5882365 milliliters, one sixteenth of a US gallon and eight US fluid ounces. It is a recipe measure rather than a general liquid unit.
It appears in American and adapted recipe books, baking charts, measuring cup sets and some packaged food directions. Outside cooking it is rarely a legal or trade unit.
The US cup is exactly eight US fluid ounces, so cup to milliliter conversions are exact at 236.5882365. Results are rounded for display, which can shift the last digit on a return conversion.
The trap is the US legal cup of 240 milliliters used on nutrition labels, and the separate metric cup of 250 milliliters; neither matches this unit. Recipe cups are also level, not heaped.
The US cup belongs with US fluid ounces and pints, while milliliters and liters belong to the metric recipe. A metric jug marked in milliliters will not match a cup measure exactly, so a recipe converted cup by cup accumulates a small error each step.
US and imperial units are kept separate because they are genuinely different sizes. Confirm which system a source means before trusting a converted figure.
The metric volume units are a clean decimal chain around the liter, so liters to milliliters is a shift of three places and cubic meters to liters is a shift of three the other way. Those pairs a reader can do without a converter.
Every pair that names a US or imperial liquid unit has to go through the definition first, because three of these units differ from a metric unit by amounts too large to round away: a liter is not a quart, a gallon is 3.785411784 liters in the US system and 4.54609 in the imperial one, and a US fluid ounce is not an imperial fluid ounce.
When checking a volume conversion, convert into liters and out again, or measure the container. The mistake that survives every other check is reading a US measure as the imperial unit of the same name, which changes a recipe, a fuel figure or a tank size by about a fifth.

20 L = 84.535057 cup
WaterAid puts the minimum daily water need per person at 20 litres, so one container is roughly one person's daily requirement.
