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 Liters
A liter (L) is the fundamental metric unit of volume, equal to one cubic decimeter (1 dm³ = 1,000 cm³ = 1,000 mL). Since its adoption as part of the metric system in 1793, the liter has become the world's most widely used volume measurement for liquids. Bottled water, soft drinks, wine, milk, and engine oil are all routinely sold by the liter globally. One liter of pure water at 4°C weighs almost exactly one kilogram - a convenient property that makes the liter central to everyday science, cooking, and industry worldwide. The liter is also written 'litre' in British English.
