Parsec to Centimeter 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 centimeter (cm) is a unit of length in the metric system equal to one-hundredth of a meter (0.01 m). It is widely used for measuring small to medium-sized objects and dimensions.

The centimeter was derived from the meter as part of the metric system's decimal structure, established in 1795. The prefix 'centi-' comes from the Latin word 'centum' meaning 'hundred'. It became popular due to its practical size for everyday measurements.

Centimeters are extensively used worldwide for measuring body dimensions (height, waist size), clothing sizes, small objects, and in medical applications. They're standard in tailoring, carpentry for precise measurements, and in many consumer products specifications.
