1 pc = 3.2618 ly
Full precision:3.2618 ly
Step-by-Step Solution

To convert 1 parsecs to light years, we multiply by 3.2618 because one parsec equals exactly 3.2618 light years.

1 parsec = 3.2618 light years

Since each parsec contains 3.2618 light years, we multiply our value by this factor:

1 × 3.2618 = 3.2618 light years

So 1 parsecs = 3.2618 light years.

Quick check: 3.2618 ÷ 3.2618 = 1 parsecs
