Why use this volume converter?
How this converter differs from a single input field
Two linked fields
Type in the liters or gallons field: the other field updates instantly, without a button or switching direction. You can choose either unit freely.
15 volume units
Liters, milliliters, centiliters, deciliters, cubic meters, gallons, quarts, pints, cups, fluid ounces, tablespoons and teaspoons: convert one volume to every unit at once.
Cooking and recipes
The ml ⇄ Cups tab starts with recipe quantities: 250 ml is 1.057 US cups, and 16 US fluid ounces is 473 ml. It also includes tables for cups, spoons, and fluid ounces.
US and UK separately
The UK gallon is about 20 percent larger than the US gallon, and pints and fluid ounces differ too. Each unit here includes its country in its name so you don’t use the wrong measure.
Exact instead of rounded
By definition, the US gallon is exactly 231 cubic inches or 3.785411784 liters, and the UK gallon is exactly 4.54609 liters. The calculator uses these definitions rather than rounded approximations.
Calculation steps and link
For each result, the calculator shows the formula with your numbers. Copy the result as a sentence or share a link with your values.
How it works
Three steps from volume to result.
Step 1
Choose a tab above: l ⇄ gal for liters and gallons, ml ⇄ Cups for recipes, or All volumes to see one volume in all 15 units at once.
Step 2
Enter the volume in a field or choose a common value. Both commas and periods work as decimal separators, and the other field updates instantly. Use the selectors below to choose units such as US gal or UK gal.
Step 3
Read the result and calculation steps, choose 0 to 4 decimal places or Auto, then copy the result or use “Share link” to copy a link with your values.

Conversion
ZAP-Hosting's free volume converter converts liters to US gallons (1 US gal = 3.785411784 l) and UK gallons (1 UK gal = 4.54609 l), and gallons back to liters. It covers 15 volume units, from cubic meters to US teaspoons. The type of gallon you choose affects the result.
Liters to US gallons
US gal = l × 0,264172
Example: 10 l × 0.264172052 = 2.642 US gal
US gallons to liters
l = US gal × 3.785411784
Example: 5 US gal × 3.785411784 = 18.927 l
The UK gallon holds 4.546 liters, making it about 20 percent larger than the US gallon at 3.785 liters. Pints and fluid ounces differ too: a UK pint is 568.261 ml, while a US pint is 473.176 ml.
As a rule of thumb, yes, but 4 liters is exactly 1.057 US gallons, about 6 percent more than one gallon. With a 50-liter tank, that adds up to around 13.209 US gallons instead of 12.5.
One US cup is 236.588 ml, one US tablespoon is 14.787 ml, and one US teaspoon is 4.929 ml. At 250 ml, a metric cup is about 5.7 percent larger than a US cup; a metric tablespoon is 15 ml.
A fluid ounce (fl oz) measures volume; a weight ounce (oz) measures mass. One US fluid ounce is 29.574 ml, and one UK fluid ounce is 28.413 ml. For water, a US fluid ounce weighs about one weight ounce, but not for oil or honey.
| Unit | US to ml | UK to ml |
|---|---|---|
| Gallon | 3,785.41 | 4,546.09 |
| Pint | 473.18 | 568.26 |
| Fluid ounce | 29.57 | 28.41 |

FAQ
Quick answers about liters to gallons, gallons to liters, ml, cups and fluid ounces.
A US gallon is exactly 3.785411784 liters (231 cubic inches), while a British (imperial) UK gallon is exactly 4.54609 liters, making it about 20 percent larger. Pints and fluid ounces differ too: a US pint is 473.18 ml, while a UK pint is 568.26 ml. That’s why the calculator labels the units US gal and UK gal.
For US gallons, multiply liters by 0.264172 or divide by 3.785411784: 50 liters is 13.21 US gallons. For UK gallons, divide by 4.54609, making 50 liters about 11 UK gallons. Enter the liters in the calculator to see the gallons and the calculation.
Multiply US gallons by 3.785411784: 5 US gallons is 18.93 liters. For UK gallons, use 4.54609, making 5 UK gallons 22.73 liters. Enter the number in the gallons field of the calculator, and the liters field fills in immediately.
One liter is 0.264172 US gallons or 0.219969 UK gallons, a little over a quarter of a US gallon. 10 liters is 2.64 US gallons or 2.2 UK gallons. For any other amount, enter the value in the liters field or choose one of the common values below the fields.
Only as a rule of thumb. More precisely, 4 liters is 1.057 US gallons, about 6 percent more than one gallon. For a 50-liter tank, the rule of thumb gives 12.5 gallons, while the calculator gives 13.21 US gallons.
A gallon measures volume, regardless of the liquid. In the US, gasoline is sold in US gallons: One gallon is 3.785 liters, and 10 gallons is 37.85 liters. Divide a price per gallon by 3.785 to get the price per liter. The calculator converts only volume, not prices or weights. Since one liter of water weighs about 1 kg, a US gallon of water weighs about 3.79 kg.
A US cup is 236.59 ml, a US tablespoon (tbsp) is 14.79 ml, and a US teaspoon (tsp) is 4.93 ml. A US fluid ounce (fl oz) is 29.57 ml, while a UK fluid ounce is 28.41 ml. The calculator uses these US and UK measures. The 250 ml metric cup is about 5.7 percent larger than a US cup: 250 ml is 1.057 US cups, which is where the ml ⇄ Cups tab starts. An ounce of weight (oz), by contrast, measures mass and is not a unit in this calculator.
15 units: liters, milliliters, centiliters, deciliters, cubic meters, US gallons, quarts, pints, cups, fluid ounces, tablespoons, and teaspoons, plus UK gallons, pints, and fluid ounces. In the All Volumes tab, you can see a volume in all 15 units at once. The calculator uses exact definitions instead of rounded factors, and you can choose 0 to 4 decimal places or let it round automatically.
The calculator is free to use without signing up. The conversion runs entirely in your browser; the calculator sends your values to no server. Whenever you change something, your values appear in your browser’s address bar (and therefore its history), so you can copy the link or share it using “Share link.”
