About Teaspoons
A teaspoon (tsp) is a US customary and cooking measurement unit equal to 1/3 of a tablespoon - approximately 4.929 mL. It is fundamental to cooking and baking worldwide: nearly every recipe in US-published cookbooks uses teaspoons as the basic small measurement for spices, baking powder, vanilla, and other minor ingredients. In medicine, over-the-counter liquid medications (especially children's doses) are measured in teaspoons, with 5 mL the standard metric equivalent used on US medication labels. Three teaspoons make one tablespoon, and six teaspoons make one fluid ounce.
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.
