Cubic Foot to Gallon Converter

A cubic foot (ft³) is a unit of volume equal to the volume of a cube with sides of exactly one foot, approximately 28.317 liters. It provides a practical volume measurement for larger spaces and materials in imperial systems.

The cubic foot developed with the imperial system as a natural extension of linear foot measurements into three-dimensional space. It became standard for measuring room volumes, construction materials, and gas quantities in countries using imperial units.

Cubic feet are widely used for room volumes, construction materials, natural gas measurements, and shipping volumes. They're standard for HVAC calculations, lumber quantities, appliance capacities, and residential space measurements in imperial systems.

A gallon (gal) is a unit of volume used primarily in the United States, equal to 231 cubic inches or approximately 3.785 liters. It serves as the primary large liquid volume measurement in the US customary system.

The gallon has ancient origins in various regional measurement systems, with the US gallon being standardized in 1832 based on the volume of 231 cubic inches of water. It became the standard liquid volume unit in the United States and differs from the imperial gallon used in the UK.

Gallons are extensively used in the United States for fuel measurements, large liquid containers, swimming pool volumes, and industrial liquid quantities. They're standard for gasoline sales, water tank capacities, and large-scale liquid measurements in the US.
