How to convert1 league (league) = 5556000 millimeter (mm). League (league) is a unit of Length used in Standard system. Millimeter (mm) is a unit of Length used in Metric system. League: A Unit of LengthThe league is an old unit of length that was common in Europe and Latin America, but is no longer official in any nation. It was derived from an ancient Celtic unit and adopted by the Romans. It was the distance a person or a horse could walk in about one hour, usually about 3 to 5 kilometers. The league varied in length from 2.4 to 4.6 statute miles in different regions. In this article, we will explore the definition, history, usage and conversion of the league as a unit of length. Definition of the LeagueThe league is a unit of length that is equal to 3 miles or 4.8 kilometers in the English-speaking countries. However, the word league often refers to the Spanish, Portuguese or French league, which have different values. The Spanish league was originally defined as 5,000 varas (a Spanish yard), about 2.6 miles or 4.2 kilometers. The Portuguese league was also 5,000 varas, but the vara was slightly longer, making the league about 2.7 miles or 4.4 kilometers. The French league was based on the nautical mile and was equal to 3 nautical miles or 5.6 kilometers. The league is not a standard unit and has no symbol. History of the LeagueThe origin of the league as a unit of length can be traced back to ancient times, when it was used as a measure of distance based on the human or animal pace. The word league comes from the Latin word leuga, which was derived from the Celtic word leuca. It referred to the distance that could be covered by a person or a horse in one hour. The league was used by the Romans, who defined it as one and a half Roman miles (7,500 Roman feet or 2.2 kilometers). The Roman league was also called leuga Gallica (the Gaulish league) or leuga Germanica (the Germanic league), depending on the region. The league was adopted by other countries that followed the Roman system of measurement, such as Spain, Portugal and France. It varied in length from country to country and from time to time, depending on local standards and methods of measurement. The league was abolished by Philip II of Spain in 1568, but it continued to be used unofficially in some parts of Latin America. The league was also incorporated into the imperial system of measurement, which was established by an act of Parliament in 1824. The imperial system was based on seven base units that could be derived from natural and traditional units. The league remained as a derived unit in the imperial system, but it was no longer recommended for use in scientific and technical fields. Usage of the LeagueThe league is a unit of length that is used for measuring long distances and dimensions, such as the length of a road or the circumference of a lake. The league is rarely used in modern times, except for historical or literary purposes. However, some countries still use it for some specific applications. For example:
Example Conversions of League to Other UnitsThe league can be converted to other units of length by using different factors and formulas. Here are some examples of conversion for different types of leagues:
1 English league x 3 = 3 miles
1 English league x 4.8 = 4.8 kilometers
1 Spanish league x 2.6 = 2.6 miles
1 Spanish league x 4.2 = 4.2 kilometers
1 Portuguese league x 2.7 = 2.7 miles
1 Portuguese league x 4.4 = 4.4 kilometers
1 French league x 3.5 = 3.5 miles
1 French league x 5.6 = 5.6 kilometers
1 mile / 3 = 0.333 English leagues 1 mile / 2.6 = 0.385 Spanish leagues 1 mile / 2.7 = 0.370 Portuguese leagues 1 mile / 3.5 = 0.286 French leagues
1 kilometer / 4.8 = 0.208 English leagues 1 kilometer / 4.2 = 0.238 Spanish leagues 1 kilometer / 4.4 = 0.227 Portuguese leagues 1 kilometer / 5.6 = 0.179 French leagues Millimeter: A Unit of LengthDefinition of the millimeterA millimeter is a unit of length in the metric system, which is based on the International System of Units (SI). It is defined as one thousandth of a meter, which is the SI base unit of length. One millimeter can be written as 1 mm or 0.001 m. How to convert millimeter to other units of lengthTo convert millimeter to other units of length, we need to use conversion factors that relate the millimeter to the desired unit. For example, to convert millimeter to centimeter, we need to know that 1 cm = 10 mm, so we can divide the number of millimeters by 10 to get the number of centimeters. Similarly, to convert millimeter to inch, we need to know that 1 in = 25.4 mm, so we can divide the number of millimeters by 25.4 to get the number of inches. Here are some common conversion factors for millimeter and other units of length in the US standard system and the SI system:
Where millimeter is usedThe millimeter is a widely used unit of length in many fields and applications around the world. Some examples are:
History of millimeterThe millimeter has a long and varied history in different countries and cultures. Some historical facts are:
