What is the Sun's radius?

The Sun's radius is the mean radius of the Sun, commonly used as an astronomical length unit equal to approximately 6.957×10^8 metres.

What is a chain [ch]?

A chain is a traditional surveying length unit equal to 66 feet or about 20.1168 metres, often used historically in land measurement.

Why convert from Sun's radius to chains?

This conversion helps translate large astronomical measurements into traditional land surveying units for integrating or comparing data across astronomy and surveying fields.

Examples

Convert 2 Sun's radius to chains: 2 × 34597947.983775 = 69195895.96755 chain
Convert 0.5 Sun's radius to chains: 0.5 × 34597947.983775 = 17298973.9918875 chain

Common Use Cases

Reporting and comparing sizes of stars using Sun's radius
Converting astronomical lengths to traditional surveying units for land measurement
Interpreting historical land deeds and survey plans that use chains
Integrating legacy property data into modern GIS systems
Analyzing stellar structures and exoplanet sizes with a terrestrial length reference

Tips & Best Practices

Use computational tools to handle very large numbers safely
Verify the unit context before applying the conversion for accuracy
Understand that the Sun's radius is an astronomical scale while chains are terrestrial
Apply conversions mainly for analytical or historical comparisons
Keep in mind the precision limits related to the astronomical unit definition

Limitations

Sun's radius is extremely large compared to chain, limiting practical everyday use
Different contexts may affect the precision due to the scientific nature of Sun's radius
Conversion results can be cumbersome without computational help because of large numbers
Chains are fixed terrestrial units, whereas the Sun's radius can be refined scientifically
Direct use of this conversion is rare outside specialized analysis or historical data comparisons
