Parsec
A parsec (pc) is a unit of distance used in astronomy, equal to about 3.26 light-years or roughly 31 trillion kilometers. The name “parsec” comes from “parallax of one arcsecond,” referring to the method astronomers use to measure distances to nearby stars based on their apparent shift when viewed from different positions in Earth’s orbit. Parsecs are commonly used to measure distances to stars and galaxies. For example, the nearest star system, Alpha Centauri, is about 1.3 parsecs away. The symbol for parsec is "pc". It’s a convenient unit for expressing large astronomical distances beyond the reach of light-years.
Vara de Tarea
The vara de tarea is a traditional Spanish and Latin American unit of area used especially in land measurement and agriculture. It combines the vara, a unit of length, with the tarea, a unit of area.
The vara is roughly 33 inches (about 0.84 meters), though it varies by region.
A tarea typically refers to an area equal to 100 square varas, but this can differ locally.
Therefore, a vara de tarea is often used to express land area based on square varas.
This unit remains in use in some rural parts of Latin America for land deeds and agricultural measurements, reflecting historical Spanish colonial measurement systems.
Summary:
Vara ≈ 0.84 meters
Tarea ≈ 100 square varas (area)
Vara de tarea = unit combining length and area for land measurement
