Disambiguation: a "mutchkin" can also refer a close-fitting Scottish cap. The mutchkin (Scottish Gaelic: mùisgein) was a Scottish unit of measurement of liquids that was in use from at least 1661, (possibly 15th century), until the late 19th century. The word was derived from mutse - a mid 15th-century Dutch measure of beer or wine. A mutchkin is equivalent to 424 ml. * 1 mutchkin is four gills (Scots), equal to three imperial gills or three quarters of an imperial pint. * 2 mutchkins is one chopin. * 4 mutchkins is one pint (Scots) (or joug), equal to three imperial pints.
