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 Deciliters

A deciliter (dL) = 0.1 L = 100 mL - the universal blood-test reporting unit: blood glucose in mg/dL, haemoglobin in g/dL, cholesterol in mg/dL, BAC in g/dL. Normal fasting glucose <100 mg/dL; dangerous BAC >0.3 g/dL. Also the primary volumetric cooking unit in Scandinavian recipes (Sweden, Norway, Denmark, Finland). 1 dL = 0.1 L.
