How to convert litres to US quarts
One litre equals 1.0567 US quarts, so multiply the number of litres by 1.0567:
US qt = L × 1.0567
L = US qt ÷ 1.0567 (1 US qt = 0.946353 L)
Example: 4 L → 4 × 1.0567 = 4.2268 US qt.
Going the other way, divide by 1.0567, or multiply by 0.946353; the US quarts to litres converter does it for you.
