Yard: A Unit of Length

A yard is a unit of length that is equal to 3 feet or 36 inches in the imperial and U.S. customary systems of measurement. It is also equal to 0.9144 meter in the International System of Units (SI). A distance of 1,760 yards is equal to 1 mile. The symbol for yard is yd.

How to Convert Yard

To convert a yard to other units of length, you can use the following formulas:

• To convert a yard to feet, multiply by 3. For example, 5 yd = 5 x 3 ft = 15 ft.
• To convert a yard to inches, multiply by 36. For example, 5 yd = 5 x 36 in = 180 in.
• To convert a yard to meters, multiply by 0.9144. For example, 5 yd = 5 x 0.9144 m = 4.572 m.
• To convert a yard to centimeters, multiply by 91.44. For example, 5 yd = 5 x 91.44 cm = 457.2 cm.
• To convert a yard to millimeters, multiply by 914.4. For example, 5 yd = 5 x 914.4 mm = 4572 mm.
• To convert a yard to kilometers, divide by 1093.6133. For example, 5 yd = 5 / 1093.6133 km = 0.00457 km.

Where Yard is Used

The yard is mainly used in the United States, the United Kingdom and some other countries that have historical ties with them. It is used for measuring length, distance, area and volume in various contexts such as:

• Sports: The yard is used for measuring the length of a football field (100 yd), the width of a soccer field (70 yd), the height of a basketball hoop (10 ft or 3.33 yd) and the distance between bases in baseball (90 ft or 30 yd).
• Textiles: The yard is used for measuring the length of fabrics and yarns (e.g., a yard of cloth, a skein of yarn).
• Construction: The yard is used for measuring the dimensions of buildings and structures (e.g., a yardstick, a cubic yard of concrete).
• Transportation: The yard is used for measuring the speed and distance of vehicles (e.g., miles per hour, yards per second).

Definition of the Yard

The current definition of the yard was established by an international agreement in 1959 as exactly 0.9144 meter. This definition was based on a prototype bronze bar that was forged in 1855 as an exact copy of the British Imperial Standard Yard held by Parliament. The prototype bar was called Bronze Yard No.11 and was the official standard of length for the United States until 1892.

The yard is defined as the length of the path travelled by light in vacuum during a time interval of

(1/299792458) × (3600/3937)

History of the Yard

The origin of the yard measure is uncertain. It may have derived from the old English unit of tax assessment called the yardland, which was equal to 1/4 hide or about 30 acres. It may also have derived from the old English unit of surveying called the rod, which was equal to 1/4 chain or about 16 (1/2) feet.

The word “yard” comes from the old English word “gerd” or “gyrd”, which meant a branch, a staff or a measuring rod. The word “yard” was first used to describe this length in William Langland’s poem Piers Plowman in the late 14th century.

The first official standard for the yard was established by King Henry I of England in the early 12th century. He ordered that the yard should be equal to the length of his arm from the tip of his nose to the end of his thumb.

The yard was also used in other countries, such as Scotland, Ireland, France and Spain, with slight variations in length. For example, the Scottish yard was equal to 37 inches, the Irish yard was equal to 40 inches, the French yard was equal to 39.37 inches and the Spanish yard was equal to 32.38 inches.

The yard underwent several changes and refinements over the centuries, until it was finally standardized as 0.9144 meter in 1959 by an international agreement between the United States, the United Kingdom, Canada, Australia, New Zealand and South Africa.

League: A Unit of Length

The 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 League

The 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 League

The 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 League

The 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:

• In Argentina, a league is equal to 5 kilometers and is used for measuring land area.
• In Brazil, a league is equal to 6 kilometers and is used for measuring distances on roads and highways.
• In Mexico, a league is variable and depends on the terrain and the mode of transportation. It is used for measuring distances between towns and villages.
• In France, a league is equal to 4 kilometers and is used for measuring distances on maps and signs.
• In Spain, a league is equal to 4 kilometers and is used for measuring distances on roads and highways.

Example Conversions of League to Other Units

The 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:

• To convert an English league to miles, multiply by 3:

1 English league x 3 = 3 miles

• To convert an English league to kilometers, multiply by 4.8:

1 English league x 4.8 = 4.8 kilometers

• To convert a Spanish league to miles, multiply by 2.6:

1 Spanish league x 2.6 = 2.6 miles

• To convert a Spanish league to kilometers, multiply by 4.2:

1 Spanish league x 4.2 = 4.2 kilometers

• To convert a Portuguese league to miles, multiply by 2.7:

1 Portuguese league x 2.7 = 2.7 miles

• To convert a Portuguese league to kilometers, multiply by 4.4:

1 Portuguese league x 4.4 = 4.4 kilometers

• To convert a French league to miles, multiply by 3.5:

1 French league x 3.5 = 3.5 miles

• To convert a French league to kilometers, multiply by 5.6:

1 French league x 5.6 = 5.6 kilometers

• To convert a mile to leagues, divide by the appropriate factor:

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

• To convert a kilometer to leagues, divide by the appropriate factor:

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
