Multiply the number of Centimeters by 3.2404×10-19 to get Parsecs. Formula: pc = cm × 3.2404×10-19. Example: 10 cm × 3.2404×10-19 = 3.2404×10-18 pc. To reverse, divide Parsecs by 3.2404×10-19 to get Centimeters.

To convert Centimeter to Parsec, multiply by 3.2404×10-19. Example: 10 cm = 3.2404×10-18 pc
To convert Parsec back to Centimeter, divide by 3.2404×10-19 (multiply by 3.086×1018). Use the swap button above.
Start with 100 Centimeters = 3.2404×10-17 pc as your reference point. Scale up or down from there.
The CGS system uses centimeters as its base length unit. When astrophysicists calculate stellar luminosities, radiation transport, or accretion rates in CGS, they convert results to parsecs for comparison with observational distance catalogues.
Computational stellar physics codes define stellar radii in centimeters (the Sun's radius = 6.96×10¹⁰ cm) while outputting results compared against stellar distance measurements in parsecs — conversion is embedded in every comparison.
1 parsec = 3.086×10¹⁸ cm — over 3 quintillion centimeters. Physics educators use cm-to-parsec to force students to work with scientific notation spanning 18 orders of magnitude in a single calculation.
X-ray telescopes measure source flux in CGS units (ergs per cm²) while source distances are in kiloparsecs. Astronomers convert between centimeter-based flux measurements and parsec-based distances in every X-ray source analysis.
Antenna dish diameters are specified in centimeters or meters, while observed source distances use parsecs or megaparsecs — radio astronomers convert between instrument scale and cosmic scale in every observation plan.
N-body simulations of galaxy formation use comoving coordinates in megaparsecs, but physical processes like star formation are calculated at centimeter scales — multi-scale codes convert between cm and parsec constantly.
The Centimeter is a unit of Length measurement (symbol: cm). 1 cm = 3.2404×10-19 pc. Used in scientific and practical Length measurement applications.
The Parsec is a unit of Length measurement (symbol: pc). It is part of an internationally recognised measurement system used alongside the Centimeter.
The centimetre was introduced in 1795 as part of the French metric system — one-hundredth of a metre, from the Latin 'centum' (hundred). The CGS (centimetre-gram-second) system, built around the centimetre, became the dominant scientific measurement system in the 19th century and remains standard in astrophysics and electromagnetism today. The centimetre is now the primary unit for human body measurements, clothing sizes, and everyday objects in most of the world.
The parsec was introduced in 1913 by British astronomer Herbert Hall Turner as a practical unit for stellar parallax measurements. It equals the distance at which 1 astronomical unit subtends 1 arcsecond — approximately 3.086×10¹³ kilometres or 3.26 light-years. The name blends 'parallax' and 'arcsecond'. Professional astronomers strongly prefer parsecs over light-years because parallax directly yields distance in parsecs without any intermediate calculation.
Common use: Centimeter to Parsec conversion is needed when working with international standards, scientific publications, or reference materials that use different unit systems for Length measurement.
