1 ly = 0.30658 pc
Full precision:0.30658 pc
Step-by-Step Solution

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

1 parsec = 3.2618 light years

Since there are 3.2618 light years in every parsec, we divide our value by this factor:

1 ÷ 3.2618 = 0.30658 parsecs

So 1 light years = 0.30658 parsecs.

Quick check: 0.30658 × 3.2618 = 1 light years

How to Convert Light Years to Parsecs

To convert light years to parsecs, divide the value by 3.2618.

The Formula

Parsecs = Light Years ÷ 3.2618

Key Fact

1 parsec = 3.2618 light years

Tip: To convert parsecs back to light years, multiply by 3.2618.

Example Conversions

Example 1: 1 ly = 0.30658 pc
1 ÷ 3.2618 = 0.30658
Example 2: 5 ly = 1.5329 pc
5 ÷ 3.2618 = 1.5329
Example 3: 10 ly = 3.0658 pc
10 ÷ 3.2618 = 3.0658
