Parsec to Hectometer Converter

A parsec (pc) is a unit of length used in astronomy, equal to approximately 3.26 light-years or 206,265 astronomical units. It is defined as the distance at which one astronomical unit subtends an angle of one arcsecond.

The parsec was defined in 1913 by British astronomer Herbert Hall Turner. The name combines 'parallax' and 'arcsecond', referring to the trigonometric parallax method used to measure stellar distances. It became the preferred unit for professional astronomical distance measurements.

Parsecs are the standard unit for measuring stellar and galactic distances in professional astronomy. They're used in stellar catalogs, galactic structure studies, and cosmological research. Kiloparsecs and megaparsecs are used for larger cosmic distances.

A hectometer (hm) is a unit of length in the metric system equal to 100 meters. It represents an intermediate measurement between meters and kilometers.

The hectometer was established as part of the original metric system in 1795. The prefix 'hecto-' derives from the Greek word 'hekaton' meaning 'hundred'. While included in the original metric system, it has seen limited adoption compared to other metric units.

Hectometers are rarely used in everyday measurements but may appear in some agricultural contexts, land surveying, and certain engineering applications. In some countries, it's occasionally used for measuring intermediate distances in rural or agricultural settings.
