Kilometers to Light Years

Convert kilometers (km) to light years (ly) with formulas, examples, and conversion tables.

Kilometers (km)

Light Years (ly)

1 km = 1.06e-13 ly

Full precision:1.06e-13 ly

Step-by-Step Solution

To convert 1 kilometers to light years, we divide by 9.46e+12 because one light year equals exactly 9.46e+12 kilometers.

1 light year = 9.46e+12 kilometers

Since there are 9.46e+12 kilometers in every light year, we divide our value by this factor:

1 ÷ 9.46e+12 = 1.06e-13 light years

So 1 kilometers = 1.06e-13 light years.

✓Quick check: 1.06e-13 × 9.46e+12 = 1 kilometers

How to Convert Kilometers to Light Years

To convert kilometers to light years, divide the value by 9.46e+12.

Light Years = Kilometers ÷ 9.46e+12

1 light year = 9.46e+12 kilometers

Tip: To convert light years back to kilometers, multiply by 9.46e+12.

Example 1: 1 km = 1.06e-13 ly
1 ÷ 9.46e+12 = 1.06e-13

Example 2: 5 km = 5.29e-13 ly
5 ÷ 9.46e+12 = 5.29e-13

Example 3: 10 km = 1.06e-12 ly
10 ÷ 9.46e+12 = 1.06e-12
