Terçon

A terçon, sometimes anglicized as tercion, is a historical French unit of liquid volume. Its value varied regionally and over time, but it was typically a fraction of a muid, a larger unit. A common approximation places it at roughly one-third of a muid, hence the name deriving from "tiers" meaning "third." However, precise equivalencies depended on the local customs and the specific liquid being measured, often wine or oil. Therefore, the precise volume a terçon represented could range significantly across different French provinces and during different historical periods. It's important to consult regional historical records to determine the specific value of a terçon in a given context.
