US Quarts: 2 ÷ 0.946353 = 2.113 US qt
US Pints: 2 ÷ 0.473176 = 4.227 US pt
US Cups: 2 ÷ 0.236588 = 8.454 US cups
Fluid Ounces: 2 ÷ 0.0295735 = 67.628 fl oz

A typical car's fuel tank holds 15 US gallons.
Liters (US): 15 × 3.78541 = 56.781 L
Liters (UK): 15 × 4.54609 = 68.191 L (if using UK gallons)
Note: US and UK gallons differ by approximately 20%.
A common water cooler jug contains 5 L of water.
US Gallons: 5 ÷ 3.78541 = 1.321 US gal
UK Gallons: 5 ÷ 4.54609 = 1.100 UK gal
US Quarts: 5 ÷ 0.946353 = 5.284 US qt
US Pints: 5 ÷ 0.473176 = 10.567 US pt
US Cups: 5 ÷ 0.236588 = 21.134 US cups
Fluid Ounces: 5 ÷ 0.0295735 = 169.07 fl oz
Milliliters: 5 × 1000 = 5000 mL
A small above-ground pool holds approximately 10,000 L of water.
US Gallons: 10000 ÷ 3.78541 = 2,641.72 US gal
UK Gallons: 10000 ÷ 4.54609 = 2,199.69 UK gal
This is equivalent to about 2,642 US gallons or 2,200 UK gallons.
The liter (L) is a metric unit of volume defined as one cubic decimeter. The gallon is a unit of volume used primarily in the United States (US liquid gallon) and the United Kingdom (UK imperial gallon). These two definitions differ significantly, making accurate conversion essential.
| Unit | Conversion Factor | Example (1 L) |
|---|---|---|
| US Gallons | 1 L = 0.264172 US gal | 1 L = 0.264 US gal |
| UK Gallons | 1 L = 0.219969 UK gal | 1 L = 0.220 UK gal |
| US Quarts | 1 L = 1.05669 US qt | 1 L = 1.057 US qt |
| US Pints | 1 L = 2.11338 US pt | 1 L = 2.113 US pt |
| US Cups | 1 L = 4.22675 US cups | 1 L = 4.227 US cups |
| US Fluid Ounces | 1 L = 33.814 US fl oz | 1 L = 33.814 fl oz |
| Milliliters | 1 L = 1000 mL | 1 L = 1000 mL |
Used in the United States and some Latin American countries. 1 US gal = 3.78541 L. Commonly used for fuel, milk, and other liquid measurements in the US.
Used in the United Kingdom, Canada, and some Commonwealth countries. 1 UK gal = 4.54609 L. About 20% larger than the US gallon.
For a rough estimate: 1 L ≈ 0.264 US gal (about ¼). Multiply liters by 0.25 for a quick approximation. For gallons to liters, multiply by 4 for a close estimate.
Most countries outside the US use the metric system (liters). The US gallon remains the standard for fuel economy, beverage containers, and cooking recipes in America.
Our Liter to Gallon Converter provides fast, accurate conversions between metric and imperial volume units. Whether you're cooking with an American recipe, calculating fuel economy, measuring pool chemicals, or working on a science project, this tool handles both forward and reverse conversions with precision.
The liter is the standard metric unit of volume used by most countries worldwide. One liter is defined as the volume of one kilogram of water at maximum density (4°C) and standard atmospheric pressure. In the imperial and US customary systems, the gallon serves a similar purpose but with different definitions.
The US liquid gallon is legally defined as 231 cubic inches, which equals approximately 3.78541 liters. It is used for most liquid measurements in the United States, including fuel, milk, and beverages. The UK imperial gallon is defined as 4.54609 liters, based on the volume of 10 pounds of water under specific conditions.
This difference matters in practical applications. For example, a car's fuel efficiency rated in miles per gallon (MPG) in the US uses US gallons, whereas the same car in the UK would be rated using imperial gallons. A US gallon of gasoline contains about 20% less volume than a UK gallon, which can significantly affect calculations in international contexts.
