Why Convert Liters to US Gallons?
Converting between liters (L) and us gallons (gal (US)) is one of the most common volume conversions. Whether for engineering, cooking, travel, or science, knowing how to quickly convert L to gal (US) saves time and prevents errors.
Volume conversions between L and gal (US) are vital for cooking, travel, and automotive contexts. The TSA 3-1-1 rule limits carry-on liquids to 100 mL (3.4 fl oz) containers — a conversion every international traveler needs. In cooking, US recipes use cups and tablespoons while metric recipes use milliliters. For automotive purposes, fuel tank capacity is measured in liters in most countries but gallons in the US.
How to Convert Liters to US Gallons
To convert liters to us gallons, use the following formula:
gal (US) = L × 0.2641720524
Example: 1 L = 0.2641720524 gal (US)
For example, 5 L = 1.320860262 gal (US), 10 L = 2.641720524 gal (US), and 100 L = 26.41720524 gal (US). Our calculator above performs this conversion instantly with full precision — no rounding errors.
Common Use Cases
- Car fuel tank (sedan): 60 L = 15.85032314 gal (US)
- Bottle of cooking oil: 5 L = 1.320860262 gal (US)
- Large water bottle: 1 L = 0.2641720524 gal (US)
- Six-pack of beer (6×330 ml): 1.98 L = 0.5230606637 gal (US)
- Standard bathtub capacity: 40 L = 10.56688209 gal (US)
Common Mistakes to Avoid
- US vs UK gallons: A US gallon (3.785 L) is smaller than a UK gallon (4.546 L). Always specify which system you're using.
- Fluid ounces vary: US fluid ounce ≠ UK fluid ounce. This converter uses US measures unless specified as UK.
- Cup measurement inconsistency: A US cup = 236.6 mL, metric cup = 250 mL, Japanese cup = 200 mL. Always verify which standard your recipe uses.
Pro Tips
- Memorize the factor: 1 L = 0.2641720524 gal (US). For quick mental math, remember this base conversion.
- Quick reference: 5 L = 1.320860262 gal (US) · 10 L = 2.641720524 gal (US) · 25 L = 6.604301309 gal (US) · 50 L = 13.20860262 gal (US) · 100 L = 26.41720524 gal (US)
