Ottoman units of measurement
Introduction The '''list of traditional Turkish units of measurement''', a.k.a. '''Ottoman units of measurement''', is given below.
History The Ottoman Empire (1299–1923), the predecessor of modern Turkey was one of the 17 signatories of the Metre Convention in 1875.For 58 years both the international and the traditional units were in use, but after the proclamation of the Turkish Republic, the traditional units became obsolete. In 1931 by Act No. 1782, international units became compulsory and the traditional units were banned from use starting 1 January 1933.

Time The traditional calendar of the Ottoman Empire was, like in most Muslim countries, the Islamic calendar. Its era begins from the Hijra in 622 CE and each year is calculated using the 12 Arabian lunar months, approximately eleven days shorter than a Gregorian solar year. In 1839, however, a second calendar was put in use for official matters. The new calendar, which was called the Rumi also began by 622, but with an annual duration equal to a solar year after 1840.In modern Turkey, the Gregorian calendar was adopted as the legal calendar, beginning by the end of 1925.But the Islamic calendar is still used when discussing dates in an Islamic context.
