Definition
A firkin is an old English unit of volume, typically used for beer, butter, or fish. It's equivalent to one-quarter of a barrel, or about nine imperial gallons (roughly 41 liters). Think of it as a historical measurement, like a medieval version of a keg 🍺. Nowadays, you're unlikely to encounter a firkin outside of historical contexts or craft breweries. The term is relatively obscure, but it offers a glimpse into the past. Imagine explaining to someone you need a firkin of pickles! 🥒
