What is Earth's polar radius?

Earth's polar radius is the distance from the Earth's center to the mean geographic pole along the rotation axis, equivalent to the semi-minor axis of the reference ellipsoid.

What is a vara de tarea?

The vara de tarea is a historical unit of length used in Spanish-speaking regions, varying by locality, mostly applied in surveying and defining land boundaries.

Why does the vara de tarea length vary?

Its exact length depends on the local historical definition, as different regions used slightly different magnitudes.

Choose 'vara de tarea' as the 'to' unit for conversion.
Perform the conversion to see the equivalent length in vara de tarea.

Key Features

Converts Earth's polar radius measurements to vara de tarea units.
Supports interpreting historical land records and cadastral data.
Helps translate precise geodetic data into regional historical units.
Useful for mapping, legal documentation, and heritage preservation.

Examples

1 Earth's polar radius equals approximately 2,537,173.67 vara de tarea.
0.5 Earth's polar radius is about 1,268,586.84 vara de tarea.

Common Use Cases

Converting geodetic measurements into historical land surveying units.
Interpreting colonial-era land deeds written in varas or vara de tarea.
Reconciling old agricultural property boundaries with modern units.
Assisting in mapping and legal documentation related to Spanish colonial regions.

Tips & Best Practices

Always verify the regional definition of vara de tarea since it varies historically.
Use this converter for general guidance and adjust for local unit variations.
Combine conversion results with contextual knowledge for accurate land record interpretation.

Limitations

Vara de tarea length varies by locality and historical context, affecting precision.
Earth's polar radius is a precise scientific measurement, whereas vara de tarea is a non-standard historical unit.
Accurate conversions require awareness of the specific regional vara de tarea definition.
