Liters to Gallons
Convert liters to gallons (US and UK). 1 L = 0.264172 US gal. For fuel comparison and liquid storage.
Tips & Notes
- ✓Quick estimate: divide liters by 3.8 for US gallons (exact: ÷3.78541). Good for fuel estimates.
- ✓1 liter ≈ 1.057 US quarts — almost a quart. Useful when buying drinks by the quart.
- ✓For UK gallons: 1 liter = 0.22 UK gal (divide by 4.546). UK gallons are larger.
- ✓Pool volumes: 1 liter = 0.264 US gallons. A 50,000 L pool = 13,209 US gallons.
Common Mistakes
- ✗Confusing US and UK gallons — 1 UK gal = 1.2 US gal. Significant difference for large volumes.
- ✗Dividing by 4 instead of 3.785 — gives UK approximate, not US. Introduces 5.7% error.
- ✗Assuming L/100km × 0.264 = mpg — fuel economy conversion is non-linear (use 235.2 ÷ L/100km).
- ✗Not adjusting for fuel density when converting liters to pounds/kg — different fuels have different densities.
Liters to Gallons Overview
What This Calculator Does
Converts liters to US gallons: 1 L = 0.264172 US gal (= 1 ÷ 3.78541). Also shows UK gallon equivalent.
Fuel Price Comparison
European fuel is priced per liter; US fuel per US gallon. To compare: multiply price-per-liter by 3.785 to get price-per-US-gallon.
| Liters | US Gallons | UK Gallons | |--------|------------|------------| | 1 L | 0.264 | 0.220 | | 10 L | 2.642 | 2.200 | | 40 L | 10.567 | 8.799 | | 50 L | 13.209 | 10.999 | | 75 L | 19.813 | 16.499 |
Common Volumes
Standard water bottle: 1.5 L = 0.396 US gal. 20-liter water cooler jug = 5.28 US gallons. A US bathtub holds about 150–190 L = 40–50 US gallons.
Frequently Asked Questions
50 × 0.264172 = 13.21 US gallons. A 50-liter European car tank holds about 13.2 US gallons.
1 liter = 0.264172 US gallons — roughly 1/4 of a gallon, or slightly more than 1 quart.
Use: mpg (US) = 235.214 ÷ L/100km. For example, 6 L/100km = 235.214 ÷ 6 = 39.2 mpg. This is not a simple liters-to-gallons conversion because fuel economy is a rate (volume per distance).
1 US gallon = 3.78541 liters — the exact definition of the US gallon.
