In 20th century Western accounts of Chinese measures, a unit of area, before 20th century reforms, said to be about 153.6 square meters (about 183.7 square yards), = ¼ mu.¹ Those are plausible values for a quarter mu in the late Qing dynasty, taking the chi at 32 centimeters (which is a surveying chi) and the mu at 6000 square chi, thus = 614.4 square meters.

But there is a problem. In Chinese a one-character word cannot end in the sound “sh”. Despite the appearance of “kish” in 20th century glossaries, the word probably never really existed.

For the same unit (¼ mu) a publication of 1856 from Canton uses “kioh” and supplies the character , which in today's pinyin is jiǎo (see jiǎo). A one-character error by a copyist may have turned “kioh” into “kish”. The change from k to j is common during this period (compare Peking and Beijing).

In Ireland, ? – 19th century, a unit of volume for fuel turf, a volume 4½ feet long by 2 feet wide, and 3 feet deep.¹ Wakefield also reports (vol. 2, page 204) that “Turf per kish” cost 2 shillings 8½ pence in Kilkenny in 1790, but 5 shillings 5 pence in 1800.

The Oxford English Dictionary (2nd ed.) derives the word from the Irish ceis, meaning basket, and defines it as a basket. Undoubtedly it had that meaning, but that another sense was a definite quantity of turf is illustrated by their own first quotation, where Arthur Young states in his Tour of Ireland (1780), “A kish of turf burns 2 barrels of lime.” There may also have been a implement for turf-cutting called a kish, since it appears among shovels and spades in Wakefield’s list of prices (page 205) at 3 shillings 3 pence in 1790, the same price as a spade, and significantly different from the price of a kish of turf. If any reader knows of such an implement, please let us know.
