About Firkins
A firkin (fir) ≈ 34.07 L (9 US gallons) - the most common cask for British real-ale delivery (9 imperial gallons = 40.91 L). A busy pub cellar cycles through several firkins per week. Craft breweries stage 'firkin tappings' of limited experimental ales. The name comes from Middle Dutch 'vierdekijn' (little fourth), as a firkin was one quarter of a barrel. 1 fir = 9 US gal ≈ 34.07 L.
About Cubic Feet
A cubic foot (ft³) is the volume of a cube with sides of one foot (30.48 cm), equal to approximately 28.317 liters. It is widely used in US construction, HVAC engineering, natural gas distribution, and real estate. Natural gas consumption is billed in cubic feet (Ccf = 100 ft³, Mcf = 1,000 ft³); refrigerator, oven, and storage compartment capacity are rated in cubic feet; and concrete or soil orders are quoted in cubic yards or cubic feet. One cubic foot of water weighs approximately 62.4 pounds. Air conditioning units are sized in BTU per hour for room volumes measured in cubic feet.
