About Pecks
A peck (pk) is a dry volume unit in the US customary system equal to 2 dry gallons or 8 dry quarts - approximately 8.810 liters. It was historically used to measure grain, produce, and bulk goods at market - a 'peck of potatoes' or 'peck of apples' was a standard quantity. The nursery rhyme 'Peter Piper picked a peck of pickled peppers' has made the peck culturally familiar even though it is rarely used in modern commerce. Four pecks equal one US bushel. In agriculture, pecks still appear in older US crop yield tables, traditional market records, and historical American cookbooks.
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.
