About this calculator
This converter translates a volume measurement from one unit into another, covering metric units like millilitres, litres, and cubic metres alongside US and imperial units like gallons, pints, and fluid ounces. It is useful in cooking, fuel efficiency comparisons, and shipping, especially since US and imperial versions of the same unit name represent different amounts.
How it works in plain English
Every supported volume unit is tied to a single base unit, the litre, through a fixed factor, and conversions pass through that shared base so that any two units can be linked accurately regardless of which measurement system they come from. Metric volumes such as millilitres, litres, and cubic metres scale in simple powers of ten.
US customary units, including US gallons, US pints, and US fluid ounces, and imperial units, including imperial gallons, imperial pints, and imperial fluid ounces, share names but represent different actual amounts because the two systems were standardized separately using different historical reference containers. An imperial gallon is noticeably larger than a US gallon, so the tool keeps these as clearly labeled, separate units rather than merging them.
Cubic feet and cubic metres are also included for describing larger volumes such as storage space, water usage, or shipping containers. To use the tool, select the unit you are starting from and the unit you want, type in a number, and the converted value updates immediately. Below the main result, a full table lists the same volume in every supported unit at once, and you can widen or narrow the decimal precision shown for the results.
The formula
- value_in_litres = value x factor_from
- result = value_in_litres / factor_to
- 1 US gal = 3.785411784 L, 1 imp gal = 4.54609 L, 1 US fl oz = 29.5735295625 mL, 1 ft³ = 28.316846592 L
Worked example
Imagine converting 2 US gallons into litres. The tool multiplies 2 by the US gallon factor, 3.785411784, giving 7.570823568 litres.
If you wanted the equivalent in imperial gallons instead, it would divide that same 7.570823568 litres by the imperial gallon factor, 4.54609, giving roughly 1.665 imperial gallons, noticeably fewer than 2 because an imperial gallon holds more liquid than a US gallon. This side-by-side comparison shows why checking which gallon a recipe, fuel economy figure, or shipping specification refers to matters before trusting a conversion, since assuming the wrong system can meaningfully change how much liquid is actually being described.

Frequently asked questions
Why are US and imperial gallons different sizes?
The two systems were standardized separately using different reference definitions in the eighteenth and nineteenth centuries. A US gallon equals 3.785411784 litres, while an imperial gallon equals 4.54609 litres, making the imperial version about 20 percent larger. This tool keeps them as separate labeled units so you always know which one you are using.
Which fluid ounce should I use for a recipe?
Check where the recipe was written. US recipes almost always mean the US fluid ounce, about 29.57 millilitres, while recipes from the United Kingdom or older Commonwealth sources may mean the imperial fluid ounce, about 28.41 millilitres. Selecting the wrong one can noticeably change liquid measurements in baking.
How does a cubic foot relate to litres?
One cubic foot equals exactly 28.316846592 litres. This unit is often used for describing appliance capacity, storage space, or water and gas usage, and the converter lets you switch between it and more familiar units like litres or US gallons without manual calculation.
Can I convert cubic metres into gallons?
Yes. Cubic metres are converted through the shared litre base value just like every other volume unit, so entering a cubic metre amount and selecting either US or imperial gallons as the target gives an accurate result, with both gallon types available separately in the results table.
How precise are the converted results?
The tool uses the exact defined conversion factors for each unit, and you can adjust the number of decimal places shown in the results to see more or fewer digits depending on whether you need a quick estimate or a precise figure for scientific or commercial use.
