15 parsecs equal approximately 49.05 light years.
Table of Contents
To convert parsecs to light years, multiply the number of parsecs by approximately 3.26156, since one parsec is about 3.26156 light years. Therefore, 15 parsecs times 3.26156 gives the result in light years, which is around 49.05.
Conversion Result and Explanation
Converting 15 parsecs to light years results in approximately 49.05 light years. This means that an object 15 parsecs away from us is about 49.05 times the distance that light travels in a year. The conversion helps understand the scale of cosmic distances in different units.

Conversion Formula
The formula to convert parsecs to light years multiplies the number of parsecs by 3.26156 because one parsec equals approximately 3.26156 light years. This conversion works because both units measure distance, with light years indicating the distance light travels in a year.
For example, if you have 10 parsecs, the calculation is 10 * 3.26156 = 32.6156 light years. Each parsec’s length in light years is fixed, making this a straightforward multiplication process to convert between them.
Conversion Example
- Convert 8 parsecs:
- Multiply 8 by 3.26156
- 8 * 3.26156 = 26.0905 light years
- So, 8 parsecs equals approximately 26.09 light years
- Convert 20 parsecs:
- Multiply 20 by 3.26156
- 20 * 3.26156 = 65.2312 light years
- Therefore, 20 parsecs equal about 65.23 light years
- Convert 5 parsecs:
- Multiply 5 by 3.26156
- 5 * 3.26156 = 16.3078 light years
- Meaning, 5 parsecs are roughly 16.31 light years away

Conversion Definitions
Parsecs
Parsecs are a unit of distance used in astronomy, representing about 3.086 x 10^13 kilometers. It measures how far away an object is based on the parallax angle, with one parsec corresponding to the distance at which a star shows a one arcsecond shift as Earth orbits.
Light
Light refers to electromagnetic radiation traveling at a constant speed of approximately 299,792 kilometers per second in vacuum. It is used as a measure of distance in space, with one light year being the distance light travels in one year, roughly 9.461 trillion kilometers.
Conversion FAQs
How accurate is the conversion from parsecs to light years?
The conversion relies on the fixed ratio of 1 parsec being approximately 3.26156 light years. While highly precise for most astronomical purposes, slight variations can occur depending on measurement methods or definitions used in specific contexts.
Why is the conversion factor 3.26156?
This number comes from the geometric relationship between parsecs and light years, derived from the parallax angle measurement of stars. It ensures that the units accurately reflect the same cosmic distances, making conversions consistent across astronomical observations.
Can I convert any number of parsecs to light years with a calculator?
Yes, by multiplying the number of parsecs by 3.26156, you can easily convert any distance in parsecs to light years. This simple calculation is reliable for all practical purposes and is used in many astronomical distance estimations.
