Decimalisation

A decimal currency is a currency in which the main unit of currency is divided by orders of magnitude in one or more subunits. Today normally is a single sub-unit, which constitutes a hundredth of the main unit.

In ancient and medieval coinage units were virtually never divided decimally. The most important vordezimale system was the Carolingian coinage. But there were some approaches to decimalization, the Roman denarius was divided into 10 aces. In Russia was already anticipated in the 16th century with a ruble to 100 kopecks, but only at the beginning of the 18th century coins were minted according to this system, and it was still the same non-decimal divisions and special name for this nominal use.

As the first country in 1792 led the United States in the decimal monetary system consistently. The U.S. dollar was at 10 Dimes (of Decimes ), divided into 100 cents and 1000 Mills. The Dime has remained as the name of the 10-cent piece, but is not used as an invoice currency. The penny, however, was the model for the hundredth classification of virtually all currencies worldwide.

The spread of decimal currency in Europe began in 1795, when France introduced the franc at 10 Decimes and 100 centimes. Again, the division had net hundreds inventory and found the Latin Monetary Union widespread. Germany was in 1871 with the introduction of the first national currency, the Mark, a decimal currency. In Austria were from 1857 100 New Cruiser 1 Gulden, at the same time were also thins and gold crowns in circulation. 1892 was introduced with the Crown to 100 Heller a purely decimal currency. Switzerland has already 1850/51 had introduced the franc of 100 centimes. As the last European countries 1971 Great Britain and Ireland shared their currency decimal. Earlier, the British and the Irish pound was divided into 20 shillings and 240 pence.

Only few states have a different distribution than by hundredths. In Tunisia, the dinar is used to 1000 millim. In Egypt, Libya and Sudan, the pound is divided into 100 piastres both and in 1000 milliemes or Millims. Bahrain, Jordan, Iraq and Kuwait expect the dinar to 1000 Fils. In the Sultanate of Oman, the national currency Rial is divided into 1000 Baisa.
