Litres to US gallons
1 litre = 0.26417 US gallons · 1 gal (US) = 3.7854 L
1 litre = 0.26417 US gallons
How it’s calculated
gal (US) = L × 0.2641720524
- Multiply the value in litres by 0.2641720524.
- To go back, divide by 0.2641720524 (or multiply by 3.785411784).
- 1 L = 0.2641720524 gal (US) · 1 gal (US) = 3.785411784 L
