Non-decimal currency Non-decimal currency A non-decimal currency is a currency that has sub-units that are a non-decimal fraction of the main unit, i.e. the number of sub-units in a main unit is not a power of 10. Today only two countries in the world use non-decimal currencies. Both of these countries are in Africa. These are Mauritania (1 ouguiya = 5 khoums) and Madagascar (1 ariary = 5 iraimbilanja). However these are only theoretically non-decimal, as in both cases the value of the main unit is so low that the sub-unit is too small to be of any practical use and coins
Decimal Day Advancement of Science and the Association of British Chambers of Commerce, followed by the success of decimalisation in South Africa, prompted the Government to set up the "Committee of the Inquiry on Decimal Currency" (Halsbury Committee) in 1961, which reported in 1963. The adoption of the changes suggested in the report was announced on 1 March 1966. The Decimal Currency Board (DCB) was created to manage the transition, although the plans were not approved by Parliament until the Decimal Currency Act in May 1969. Former Greater London Council leader Bill Fiske was named as the Chairman of the Decimal Currency
