What is Earth's equatorial radius used for?

It serves as a geodetic standard for defining reference ellipsoids, map projections, and is used in aerospace engineering for satellite orbit calculations.

Why convert from Earth's equatorial radius to reed?

Converting to reed helps interpret historical land records, archaic maps, and supports ethnographic or archaeological research involving traditional units.

Is the reed a consistent measurement unit?

No, the reed varies historically and regionally, so its exact length differs depending on time and place.

Select Earth's equatorial radius as the source unit
Choose reed as the target unit for conversion
Click the convert button to get the equivalent length in reed

Key Features

Converts between Earth's equatorial radius and reed units of length
Supports applications in geodesy, aerospace, historical, and ethnographic research
Provides easy-to-understand conversion steps and examples
Facilitates interpretation of archaic maps and documents using the reed unit

Examples

1 Earth's equatorial radius equals 2,325,080.20 reed
0.5 Earth's equatorial radius equals 1,162,540.10 reed

Common Use Cases

Defining coordinate systems and map projections in geodesy and cartography
Calculating satellite orbits and ground range in aerospace engineering
Interpreting historical land records and archaic measurement systems
Supporting ethnographic and archaeological studies of traditional length units
Analyzing legal documents involving obsolete regional units of length

Tips & Best Practices

Use the converter for large-scale measurements due to the Earth's equatorial radius's immense size
Verify the historical context when working with the reed as its value varies regionally and over time
Leverage this tool when translating modern geodetic data to historical or regional scales
Apply the converter to aid archaeological and ethnographic analysis involving traditional measurement units

Limitations

The reed unit varies historically and regionally, making exact equivalences vary by location and period
Earth's equatorial radius is too large for practical small-scale measurements
The reed is obsolete and not commonly used in current scientific contexts outside historical research
