It was only in 1867 that the term " kilometer " became the only official unit of measure in the Netherlands to represent 1000 metres. ![]() The Dutch, on the other hand, adopted the kilometre in 1817 but gave it the local name of the mijl. French maps published in 1835 had scales showing myriametres and " lieues de Poste " (Postal leagues of about 4288 metres). The term " myriamètre" appeared a number of times in the text of Develey's book Physique d'Emile: ou, Principes de la science de la nature, (published in 1802), while the term kilometre only appeared in an appendix. The first name of the kilometre was "Millaire".Īlthough the metre was formally defined in 1799, the myriametre ( 10 000 metres) was preferred to the "kilometre" for everyday use. In August 1793, the French National Convention decreed the metre as the sole length measurement system in the French Republic and it was based on 1 / 10 millionth of the distance from the orbital poles (either North or South) to the Equator, this being a truly internationally based unit. Historical divisions of the meridian in Franceīy a decree of, the French National Constituent Assembly ordered the French Academy of Sciences to develop a new measurement system. Equivalence to other units of length 1 kilometre However, the Australian prime minister at the time, Gough Whitlam, insisted that the second pronunciation was the correct one because of the Greek origins of the two parts of the word. When Australia introduced the metric system in 1975, the first pronunciation was declared official by the government's Metric Conversion Board. This pronunciation is irregular because this makes the kilometre the only SI unit in which the stress is on the second syllable. The contrast is even more obvious in countries which use the Commonwealth spelling rather than American spelling of the word metre. The second pronunciation follows the stress pattern used for the names of measuring instruments (such as micrometer, barometer, thermometer, tachometer and speedometer). Many other users, particularly in countries where the metric system is not widely used, use the second pronunciation with stress on the second syllable. It is generally preferred by the British Broadcasting Corporation (BBC), the Canadian Broadcasting Corporation (CBC), and the Australian Broadcasting Corporation (ABC). The first pronunciation follows a pattern in English whereby metric units are pronounced with the stress on the first syllable (as in kilogram, kilojoule and kilohertz) and the pronunciation of the actual base unit does not change irrespective of the prefix (as in centimetre, millimetre, nanometre and so on). There are two common pronunciations for the word. ( October 2011) ( Learn how and when to remove this template message) Unsourced material may be challenged and removed.
