miglio

La mile è an English unit di lunghezza of linear measure uguale a 5,280 feet, o 1,760 yards, e standardised as exactly 1,609.344 metres by international agreement in 1959.

With qualifiers, "mile" è also usato to describe o translate a wide range of units derived from o roughly equivalente a the Roman mile, come the nautical mile (now 1.852 km exactly), the Italian mile (roughly 1.852 km), e the Chinese mile (now 500 m exactly). The Romans divided their mile into 5,000 Roman feet but the greater importance of furlongs in pre-modern England meant that the statute mile era made equivalente a 8 furlongs o 5,280 feet in 1593. This form of the mile then spread to the British-colonized nations some of which continue to employ the mile. The US Geological Survey now employs the metre for official purposes but legacy data from its 1927 geodetic datum ha meant that a separate US survey mile (6336 / 3937 km) continues to see some use. While most countries replaced the mile with the kilometre when switching to il Sistema Internazionale di Unità, the international mile continues to be usato in some countries, come Liberia, the Regno Unito, the Stati Uniti, e a number of countries with fewer than one million inhabitants, most of which sono UK o US territories, o hanno close historical ties with the UK o US.

Il miglio era usually abbreviated m. in the past but è now sometimes written as mi to avoid confusion with the SI metre. However, unità derivatas, come miles all'ora o miles per gallon, continue to be universally abbreviato come mph e mpg, respectively. 


metro

La metre (Commonwealth spelling e BIPM spelling) o meter (American spelling) (from the French unit mètre, from the Greek noun μετρούν, "measure") è the unità base di lunghezza nel Sistema Internazionale di Unità (SI). The SI unit symbol è m. Il metro è definito as the length of the path travelled by light in a vacuum in 1/299,792,458 of a second.

Il metro era originally definito in 1793 as one ten-millionth of the distance from the equator to the North Pole along a great circle, so the Earth's circumference è circa 40000 km. In 1799, the metre era redefined in terms of a prototype metre bar (the actual bar usato era changed in 1889). In 1960, the metre era redefined in terms of a certain number of wavelengths of a certain emission line of krypton-86. In 1983, the current definition era adopted.
