1 gallon ≈ 3.8 liters ≈ a large milk jug. 4 quarts = 1 gallon. A gallon of water weighs about 8.3 pounds.
About Cubic Foot (ft³)
Definition
The cubic foot is an imperial unit of volume equal to the space occupied by a cube one foot on each side (1,728 cubic inches).
Mathematical Relationship
1 ft³ = 1,728 in³ = 28.3168 L = 0.0283168 m³. There are 27 ft³ in one cubic yard.
Conversion Formula
To liters: multiply by 28.3168. To gallons (US): multiply by 7.48052. To cubic meters: multiply by 0.0283168.
