An old Arabic unit. Also romanized as oka, occa, ocka, ocque, oque, ocao, occhia.  Primarily a unit of mass (= 400 drachmes).

In Turkey, two units, one of mass and one of liquid capacity.

At least as early as the 14th century – 19th century, a unit of mass, about 2.834 pounds avoirdupois.

For Smyrna, Hayes (1740, page 410) reported the oke (which he spelled “oak”) = 400 “drams”, and was about 2 pounds 11 ounces avoirdupois (about 1.219 kilograms). But he also says 1 avoirdupois pound is 140 drams, making the oke 1.296 kg. There were special okes for some high-value commodities: an oke of opium was 250 drams (about 810 grams, using Hayes’ equivalent for a pound), an oke of saffron was 120 drams (about 388 grams).

On 24 August 1821, the London Mint compared British standards with a set of weights certified as accurate on 10 April 1821 by the official in Constantinople responsible for such certification (see Kelly, 1835, volume 1, page 376). They obtained the value 1 oke = 19800 English troy grains, equivalent to 1.283 kilograms or 2.828 pounds av. (about 2 pounds 13¼ ounces).

The standards of Constantinople and Smyrna apparently differed, though theoretically identical.
