Gigaparsec To Thou (Gpc To Thou) Converter

The Gigaparsec To Thou (Gpc To Thou) Converter is a specialized tool designed to help users easily convert distances measured in gigaparsecs (Gpc) to thou (thousandths of an arcsecond). This is particularly useful in fields like astronomy and astrophysics, where precise measurements of vast cosmic distances are essential.

A gigaparsec (Gpc) is a unit of distance used in astronomy to describe extremely large scales. One gigaparsec equals one billion parsecs, and one parsec (pc) is approximately 3.086 x 10¹⁶ meters. In formula form:
1 Gpc = 10⁹ parsecs.

A thou (thousandth of an arcsecond) is a unit of angular measurement. An arcsecond (“) is 1/3600 of a degree, and a thou is 1/1000 of an arcsecond, making it a very small angle. To convert a distance in gigaparsecs to an angular measurement in thou, the tool uses the relationship between distance and angle based on the small-angle approximation.

The core formula used in the conversion is:
Angle (in arcseconds) = (206265 * parsecs) / distance (in parsecs).
Since 1 Gpc = 10⁹ parsecs, the formula adapts accordingly to convert gigaparsecs to an angular measurement in thou. The converter automates this calculation, allowing you to input a distance in gigaparsecs and receive the equivalent angular measurement in thou instantly.
