Convert liters to gallons (US & Imperial) for fuel economy, beverage sizes, and liquid volumes. Understand the difference between US and UK gallons.
1 liter equals 0.264172 gallon
Formula: gal = L × 0.264172
Converting liters to gallons is essential for understanding fuel economy, beverage sizes, and liquid measurements across different countries. This converter handles both US gallons (3.785 liters) and Imperial/UK gallons (4.546 liters), helping you navigate the complexities of international liquid measurements.
With global travel, international trade, and online shopping, understanding liter to gallon conversion is increasingly important. Fuel efficiency comparisons, beverage industry standards, and chemical handling all require accurate conversion between metric and imperial volume measurements. The existence of two different gallon standards adds complexity that this converter helps resolve.
Fuel economy is measured differently worldwide - L/100km, km/L, MPG (US), and MPG (UK). Understanding these conversions helps compare vehicle efficiency and fuel costs internationally.
Beverage packaging varies by country. US uses fluid ounces and gallons, while most countries use liters and milliliters. This affects everything from soft drinks to milk packaging.
Industrial liquids, chemicals, and bulk materials are often traded internationally, requiring precise conversion between metric and imperial systems for safety and compliance.
| liters | gallons |
|---|---|
| 10 L | 2.64172 gal |
| 50 L | 13.2086 gal |
| 100 L | 26.4172 gal |
| 500 L | 132.086 gal |
| 1000 L | 264.172 gal |
Formula: gal = L × conversion factor

Historical accident. The US gallon is based on the Queen Anne wine gallon (1707), while the Imperial gallon was redefined in 1824 as the volume of 10 pounds of water. When Britain updated their system, the US had already standardized on the older definition. Canada used Imperial gallons until metrication in the 1970s. Today only the US, Liberia, and Myanmar use US gallons.
It's tricky because they use opposite systems. US uses MPG (miles per gallon) - higher is better. Europe uses L/100km (liters per 100 kilometers) - lower is better. To convert: MPG(US) = 235.21 ÷ L/100km. For example, 7 L/100km = 33.6 MPG(US). Remember UK MPG is different due to Imperial gallons: MPG(UK) = 282.48 ÷ L/100km.
Very few. The US, Myanmar, and Liberia use US gallons. Some Caribbean nations like Antigua, Cayman Islands, and parts of the Bahamas also use US gallons due to American influence. The UK switched to liters for fuel in the 1980s but older people still think in gallons. Belize and some other former British territories may reference Imperial gallons informally.
It's about volume standards. US milk comes in gallons (3.785L), half-gallons, quarts, and pints. Canadian milk comes in 4L, 2L, 1L bags or cartons - slightly more than US equivalents. The 4L Canadian jug is 5.7% larger than a US gallon, which is why they feel bigger. The shape also differs due to metric sizing.
Depends on use. Cooking: 5% accuracy is usually fine. Fuel calculations: 1% accuracy recommended. Chemicals/medicine: 0.1% or better. Use 3.785 for US gallons and 4.546 for Imperial gallons. For estimates: 1 US gal ≈ 3.8L, 1 UK gal ≈ 4.5L. Temperature affects volume - liquids expand about 1% per 20°C change.
