About these units
Parsec (pc)
A parsec is equal to 3.26 light years, or approximately 3.0857 × 10¹⁶ meters. It is defined based on the method of stellar parallax, the apparent shift in a star's position caused by Earth's orbit around the Sun. Specifically, a star at a distance of one parsec exhibits a parallax angle of one arcsecond (1/3600 of a degree). Because its definition emerges directly from geometric measurement techniques, the parsec became the standard astronomical unit for professional research. Parallax-based distances are foundational to the cosmic distance ladder — the sequence of methods by which astronomers measure distances from nearby stars to the farthest galaxies. The parsec is widely used in astrophysics because calculations involving gravitational dynamics, luminosity, or galactic structure often become more intuitive in parsecs than in light years. Although less familiar to the public, it is the preferred unit in scientific publications, planetary catalogs, and distance mapping of the Milky Way.
Foot (US Survey) (ft (US))
The US Survey Foot is a standardized version of the foot, defined as exactly 1200/3937 meters (~0.30480061 m). It was adopted to maintain continuity with older surveying records when converting to the metric system. Surveyors, engineers, and geographers in the United States used this unit for mapping, cadastral surveys, and infrastructure projects. Its slight difference from the international foot allows historical survey data to align accurately with modern geodetic coordinates. Although the international foot is now more common, the US survey foot remains relevant for interpreting historical survey data and legal property boundaries.
