Puerto Rican Units Of Measurement
Several units of measurements are used in Puerto Rico. The units of measure in use in Puerto Rico are based on the United States customary units with two major exceptions: roadway distance signs are measured in kilometers and gasoline is sold by the liter. System before US customary units Several units were used before the US takeover in 1898. These units were older Spanish units. Area Several units were used to measure area. Among them were the ''cuerda'' and the '' caballería''. ''Cuerda'' In Puerto Rico, a ''cuerda'' is a traditional unit of land area nearly equivalent to 3,930 square meters, or 4,700 square yards, 0.971 acre, or 0.393 hectare (ha). The precise conversion is 1 cuerda = 3,930.395625 m2. The term "Spanish acre" instead has been used sometimes by mainlanders. A cuerda and an acre have often been treated as equal because they are nearly the same size. It continues to be an official unit of land measure in Puerto Rico today (2019).

Units Of Measurement
A unit of measurement is a definite magnitude (mathematics), magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity. Any other quantity of that kind can be expressed as a multiple of the unit of measurement. For example, a length is a physical quantity. The metre (symbol m) is a unit of length that represents a definite predetermined length. For instance, when referencing "10 metres" (or 10 m), what is actually meant is 10 times the definite predetermined length called "metre". The definition, agreement, and practical use of units of measurement have played a crucial role in human endeavour from early ages up to the present. A multitude of System of measurement, systems of units used to be very common. Now there is a global standard, the International System of Units (SI), the modern form of the metric system.

United States Customary Units
United States customary units form a system of measurement units commonly used in the United States and U.S. territories since being standardized and adopted in 1832. The United States customary system (USCS or USC) developed from English units which were in use in the British Empire before the U.S. became an independent country. The United Kingdom's system of measures was overhauled in 1824 to create the imperial system, which was officially adopted in 1826, changing the definitions of some of its units. Consequently, while many U.S. units are essentially similar to their imperial counterparts, there are significant differences between the systems. The majority of U.S. customary units were redefined in terms of the meter and kilogram with the Mendenhall Order of 1893 and, in practice, for many years before. T.C. Mendenhall, Superintendent of Standard Weights and MeasuresOrder of April 5, 1893, published as Appendix 6 to the Report for 1893 of the United States Coast and G ...

Litre
The litre (international spelling) or liter (American English spelling) (SI symbols L and l, other symbol used: ℓ) is a metric unit of volume. It is equal to 1 cubic decimetre (dm3), 1000 cubic centimetres (cm3) or 0.001 cubic metre (m3). A cubic decimetre (or litre) occupies a volume of (see figure) and is thus equal to one-thousandth of a cubic metre. The original French metric system used the litre as a base unit. The word ''litre'' is derived from an older French unit, the '' litron'', whose name came from Byzantine Greek—where it was a unit of weight, not volume—via Late Medieval Latin, and which equalled approximately 0.831 litres. The litre was also used in several subsequent versions of the metric system and is accepted for use with the SI,Bureau International des Poids et M ...

Caballería
The () was a unit of land measurement in the Spanish viceroyalties in the Americas during the times of the Spanish Empire in the 16th through 19th centuries Spanish West Indies. The unit was widely used in Puerto Rico, where it was equivalent to . The unit, however, came from Spain, where it had already been in use. History A decree of King Ferdinand V on 18 June 1513 is the first known law granting land in the Americas to Europeans. The decree dictated that conquered lands could be granted to Spanish soldier in two units: caballerías and peonias. The decree extended to the New World a system Castile had already been using for areas it conquered in Europe. While a "peonia" was the amount of land granted a retiring foot soldier, a was the amount granted to a retiring cavalryman. The unit was over four times larger than a peonia. Land grants measuring one or more were issued to the members of the cavalry of a Spanish war company upon resulting victorious over a territory ...

Square Meter
The square metre ( international spelling as used by the International Bureau of Weights and Measures) or square meter (American spelling) is the unit of area in the International System of Units (SI) with symbol m2. It is the area of a square with sides one metre in length. Adding and subtracting SI prefixes creates multiples and submultiples; however, as the unit is exponentiated, the quantities grow exponentially by the corresponding power of 10. For example, 1 kilometre is 103 (one thousand) times the length of 1 metre, but 1 square kilometre is (103)2 (106, one million) times the area of 1 square metre, and 1 cubic kilometre is (103)3 (109, one billion) cubic metres. SI prefixes applied The square metre may be used with all SI prefixes used with the metre. Unicode characters Unicode has several characters used to represent metric area units, but these are for compatibility with East Asian character encodings and are meant to be used in new documents. * * * * ...

Hectare
The hectare (; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100-metre sides (1 hm2), or 10,000 m2, and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about and one hectare contains about . In 1795, when the metric system was introduced, the ''are'' was defined as 100 square metres, or one square decametre, and the hectare ("hecto-" + "are") was thus 100 ''ares'' or km2 (10,000 square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units (), the ''are'' was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI and whose use is "expected to continue indefinitely". Though the dekare/decare daa (1,000 m2) and are (100 m2) are not officially "accepted for use", they are still used in some contexts. Description The hectare (), although not a unit of SI, i ...

Spanish Colonization Of The Americas
Spain began colonizing the Americas under the Crown of Castile and was spearheaded by the Spanish . The Americas were invaded and incorporated into the Spanish Empire, with the exception of Brazil, British America, and some small regions of South America and the Caribbean. The crown created civil and religious structures to administer the vast territory. The main motivations for colonial expansion were profit through resource extraction and the spread of Catholicism by converting indigenous peoples. Beginning with Columbus's first voyage to the Caribbean and gaining control over more territory for over three centuries, the Spanish Empire would expand across the Caribbean Islands, half of South America, most of Central America and much of North America. It is estimated that during the colonial period (1492–1832), a total of 1.86 million Spaniards settled in the Americas, and a further 3.5 million immigrated during the post-colonial era (1850–1950); the esti ...

Spanish Empire
The Spanish Empire ( es, link=no, Imperio español), also known as the Hispanic Monarchy ( es, link=no, Monarquía Hispánica) or the Catholic Monarchy ( es, link=no, Monarquía Católica) was a colonial empire governed by Spain and its predecessor states between 1492 and 1976. One of the largest empires in history, it was, in conjunction with the Portuguese Empire, the first to usher the European Age of Discovery and achieve a global scale, controlling vast portions of the Americas, territories in Western Europe], Africa, and various islands in Spanish East Indies, Asia and Oceania. It was one of the most powerful empires of the early modern period, becoming the first empire known as "the empire on which the sun never sets", and reached its maximum extent in the 18th century. An important element in the formation of Spain's empire was the dynastic union between Isabella I of Castile and Ferdinand II of Aragon in 1469, known as the Catholic Monarchs, which in ...
