"Vara de tarea" is a term that can be translated from Spanish to mean "task pole" or "work pole." In some Spanish-speaking regions, particularly in Mexico and parts of Central America, "vara de tarea" is a traditional unit of length used to measure land.
The length of a "vara de tarea" can vary by region, but it is typically around 4 meters (approximately 13.1 feet) or slightly longer. It was historically used for land measurement, especially in rural and agricultural areas, to define property boundaries and land plots for farming or other tasks.
It's important to note that "vara de tarea" is a localized and regional unit of measurement and may not be widely recognized or used in other Spanish-speaking countries or regions. The use of standardized metric or imperial units is more common in modern times.
A "span" is a traditional unit of length used for measuring cloth or fabric. It was historically used in various countries, including England, and is based on the width of the human hand or the spread of the fingers. The actual length of a span could vary depending on the region and historical context.
In England, a span was typically equal to 9 inches or approximately 22.86 centimeters. However, it's important to note that the definition of a span could vary from place to place and over time.
