Vara De Tarea
The vara de tarea is a Spanish colonial unit of length used in parts of Latin America, particularly associated with agricultural land measurement. It is a variant of the vara, a traditional Iberian unit whose length varied by region, typically ranging between 0.8 and 0.9 meters. The vara de tarea was used specifically in the context of assigning agricultural work tasks, where a tarea represented the area a worker could cultivate in a day.
Meter
The metre (Commonwealth spelling and BIPM spelling) or meter (American spelling) (from the French unit mètre, from the Greek noun μετρούν, "measure") is the base unit of length in the International System of Units (SI). The SI unit symbol is m. The metre is defined as the length of the path travelled by light in a vacuum in 1/299,792,458 of a second.
The metre was originally defined 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 is approximately 40000 km. In 1799, the metre was redefined in terms of a prototype metre bar (the actual bar used was changed in 1889). In 1960, the metre was redefined in terms of a certain number of wavelengths of a certain emission line of krypton-86. In 1983, the current definition was adopted.
