Frequently Asked Questions

About Cubic Foot and UK Gallon

Cubic Foot (ft³)

The cubic foot is the Imperial and US customary volume unit equal to the space occupied by a cube with one-foot sides. It was formally standardized in the UK by the Weights and Measures Act of 1824.

Cubic feet appear in HVAC (airflow in CFM), natural gas billing in the US, and real-estate appraisals. One cubic foot equals exactly 1,728 cubic inches or approximately 28.317 liters.

Interesting fact: US natural gas meters read in CCF (hundreds of cubic feet) or MCF (thousands), making the cubic foot the invisible unit behind most American gas utility bills.

UK Gallon (gal(UK))

The Imperial gallon was defined by the British Weights and Measures Act of 1824 as the volume of ten pounds of water at 62°F, later fixed to exactly 4.54609 liters in 1985.

UK gallons are still used in Britain for fuel pricing. Road signs show consumption in miles per Imperial gallon, making UK cars appear more fuel-efficient than identical US models.

Interesting fact: 1 Imperial gallon = 1.20095 US gallons. Confusing the two has caused real-world errors in cross-border fuel cost calculations.
