Volume reference: fuel tanks and liquid containers
| Liters | US Gallons | Typical use |

| 5 L | 1.3209 gal | Small jerry can |
| 10 L | 2.6417 gal | Bucket capacity |
| 20 L | 5.2834 gal | Standard fuel can |
| 50 L | 13.2086 gal | Average car fuel tank |

Fuel economy, tanks and containers
When comparing fuel efficiency figures across markets, liters-to-gallons comes up constantly. European cars are rated in liters per 100 km (L/100km); US EPA ratings use miles per gallon. A compact car rated 6 L/100km is roughly equivalent to 39 mpg US, not 6 mpg. The distance dimension flips the comparison, but knowing that 1 US gallon = 3.785 liters is the starting point for the full calculation.
Container and tank sizes also split by market. A standard 5-liter jerry can holds 1.32 US gallons. A 20-liter container common for camping water storage holds 5.28 US gallons. A typical 60-liter European car fuel tank holds 15.85 US gallons. If you fill up abroad and want to compare the cost against home pump prices, dividing liters by 3.785 gives you the gallon equivalent for the receipt math.
UK and US gallons are not the same. One UK (Imperial) gallon equals 4.546 liters, about 20% more than a US gallon. A recipe or fuel spec written in the UK means something different from one written in the US even when both say "gallon". This converter uses US gallons; if you need UK gallons, divide liters by 4.546 instead.
Frequently Asked Questions
How many liters does a full tank of gas hold?
A compact car fuel tank typically holds 40-55 liters (10.5-14.5 US gallons). A family sedan holds 55-70 liters (14.5-18.5 US gallons). SUVs and trucks range from 75-100 liters (19.8-26.4 US gallons). If a US fuel receipt lists gallons, multiply by 3.785 to get liters for your own records.
Are US and UK gallons the same?
No. One US gallon equals 3.785 liters, but one UK (Imperial) gallon equals 4.546 liters. The UK gallon is about 20% larger. This converter uses US gallons.
A recipe calls for 2 gallons of water, how many liters is that?
2 US gallons = 7.57 liters. Common amounts: 1 quart (0.25 gal) = 0.946 liters, 1 gallon = 3.785 liters, 2 gallons = 7.57 liters. European recipes use liters directly. For a US slow cooker recipe that specifies gallons, convert once and note the liter equivalent on the recipe card.
Why does a UK gallon give me a different result than a US gallon?
One US gallon = 3.785 liters; one UK (Imperial) gallon = 4.546 liters. The difference is 20%. If you fill up a UK car and the receipt shows 10 gallons, that's 45.46 liters, not 37.85. This converter uses US gallons. For UK gallon conversions, the factor is 4.546.
Can I convert milk and water the same way?
Yes. All liquids use the same volume conversion. The factor 0.264172 applies whether you measure water, milk, fuel or oil.
Why does a 5-liter jug sometimes look different in gallons on different package labels?
The same container (5 liters) can be labeled as either 1.32 US gallons OR 1.10 UK gallons, depending on where it was manufactured. A 5-liter container is standard in metric countries. Always check which gallon system (US or UK) the label uses before assuming equivalence. For cooking, US measurements are more common in English-language recipes; check recipe sources.
How much water should I drink daily, and how does that convert?
A common recommendation is 2-3 liters per day (0.53-0.79 US gallons). That's roughly 8-12 standard cups per day. If you prefer US measurements, a gallon of water daily (3.785 liters) is roughly double the typical recommendation. Track your intake in the unit system that makes sense to you, either way, consistency matters more than the unit.
