✓Quick check: 5.8788e+12 ÷ 5.8788e+12 = 1 light years

How to Convert Light Years to Miles

To convert light years to miles, multiply the value by 5.8788e+12.

Miles = Light Years × 5.8788e+12

1 light year = 5.8788e+12 miles

Tip: To convert miles back to light years, divide by 5.8788e+12.

Example 1: 1 ly = 5.8788e+12 mi
1 × 5.8788e+12 = 5.8788e+12

Example 2: 5 ly = 2.9394e+13 mi
5 × 5.8788e+12 = 2.9394e+13

Example 3: 10 ly = 5.8788e+13 mi
10 × 5.8788e+12 = 5.8788e+13
