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 Quarts
A quart (qt) is a US customary volume unit equal to 2 pints or 4 cups - approximately 946.353 mL (just under one liter). Motor oil, paint, and large containers of juice or milk are commonly sold by the quart in the United States. The term 'quart' derives from the Latin 'quartus' (fourth), as it is one quarter of a gallon. The US liquid quart (946 mL) differs from the UK imperial quart (1136 mL). Engine coolant, transmission fluid, and many automotive products are measured and sold in quart containers in the US. Four quarts equal one US gallon.
