Astronomy Converter
Convert astronomical length, mass, time, and distance units by compatible family.
Context values
Some unit families need one extra value for a physically accurate result.
Use the converter to see the formula.
Parsec measures distance and Century measures time, so choose two units from the same family for a direct result.

Formula
Parsec and Century measure different physical quantities (distance and time), so there is no single fixed multiplication factor between them.
The astronomy converter is dimension-aware: pick two distance units, or two time units, to get a direct, exact result.
Conversion table
Because parsec (distance) and century (time) measure different physical quantities, there is no meaningful numeric conversion table between them.

Frequently asked questions
What is parsec?
A parsec is the distance at which one astronomical unit subtends one arcsecond, about 3.26156 light-years.
What is century?
A century is 100 average Gregorian years.
Can I convert parsec to century?
Not directly. Parsec is a distance unit and Century is a time unit, and the astronomy converter keeps these families separate so results stay physically meaningful.
Why doesn't the converter give a result for this pair?
Converting between distance and time would require an extra physical assumption (such as a specific object's density, composition, or motion), which isn't a fixed constant the way distance-to-distance or time-to-time factors are.
What should I use parsec for?
Use parsec together with other distance units, such as the ones listed under related conversions below.
What should I use century for?
Use century together with other time units to get an exact, dimension-consistent result.

About this conversion
This page compares parsec (pc) and century (century) inside the astronomy converter.
A parsec is the distance at which one astronomical unit subtends one arcsecond, about 3.26156 light-years.
A century is 100 average Gregorian years.
Parsec measures distance while Century measures time. Because these are different physical dimensions, the astronomy converter does not produce a direct numeric result for this pair — the same way a length can't be converted to a mass without extra information.
Open the calculator above and pick two units from the same family (distance with distance, or time with time) for an instant, exact conversion.
