Cubic feet to Milliliters
One cubic feet is 28,316.846592 milliliters, and one milliliters is 3.5315e-5 cubic feet.
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 ft³= 28,316.846592 mL
- 2 ft³= 56,633.693184 mL
- 5 ft³= 141,584.23296 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.
Cubic feet to Liters
One cubic feet is 28.316847 liters, and one liters is 0.035315 cubic feet.
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 ft³= 28.316847 L
- 2 ft³= 56.633693 L
- 5 ft³= 141.584233 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.
Cubic feet to Cubic meters
One cubic feet is 0.028317 cubic meters, and one cubic meters is 35.314667 cubic feet.
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 ft³= 0.028317 m³
- 2 ft³= 0.056634 m³
- 5 ft³= 0.141584 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.
Cubic feet to Cubic centimeters
One cubic feet is 28,316.846592 cubic centimeters, and one cubic centimeters is 3.5315e-5 cubic feet.
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 ft³= 28,316.846592 cm³
- 2 ft³= 56,633.693184 cm³
- 5 ft³= 141,584.23296 cm³
Cubic feet to Cubic inches
One cubic feet is 1,728 cubic inches, and one cubic inches is 5.787e-4 cubic feet.
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 ft³= 1,728 in³
- 2 ft³= 3,456 in³
- 5 ft³= 8,640 in³
Cubic feet to US gallons
One cubic feet is 7.480519 us gallons, and one us gallons is 0.133681 cubic feet.
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 ft³= 7.480519 gal
- 2 ft³= 14.961039 gal
- 5 ft³= 37.402597 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.
Cubic feet to US quarts
One cubic feet is 29.922078 us quarts, and one us quarts is 0.03342 cubic feet.
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 ft³= 29.922078 qt
- 2 ft³= 59.844156 qt
- 5 ft³= 149.61039 qt
Cubic feet to US pints
One cubic feet is 59.844156 us pints, and one us pints is 0.01671 cubic feet.
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 ft³= 59.844156 pt
- 2 ft³= 119.688312 pt
- 5 ft³= 299.220779 pt
Cubic feet to US fluid ounces
One cubic feet is 957.506494 us fluid ounces, and one us fluid ounces is 0.001044 cubic feet.
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 ft³= 957.506494 fl oz
- 2 ft³= 1,915.012987 fl oz
- 5 ft³= 4,787.532468 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.
Cubic feet to Imperial gallons
One cubic feet is 6.228835 imperial gallons, and one imperial gallons is 0.160544 cubic feet.
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 ft³= 6.228835 imp gal
- 2 ft³= 12.457671 imp gal
- 5 ft³= 31.144177 imp gal
Cubic feet to US cups
One cubic feet is 119.688312 us cups, and one us cups is 0.008355 cubic feet.
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.
- 1 ft³= 119.688312 cup
- 2 ft³= 239.376623 cup
- 5 ft³= 598.441558 cup
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.
What cubic feet are used for
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.
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.
The cubic foot is defined through the foot, so its liter value is exact at 28.316846592. Only the displayed result is rounded, and a value taken to cubic meters and back may return with the final digit changed.
The error is confusing a cubic foot with a square foot or with a foot; volume needs three dimensions. Another is using the cubic foot where a liquid measure such as the liter or gallon is expected.
Cubic feet and cubic meters divide the same volume on different scales, and liters appear on appliance and gas labels. One cubic meter is about 35.3 cubic feet, so a figure copied between them without conversion is wrong by more than thirtyfold.
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.

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