🌌 What Is a Light Year?
A light year is the distance light travels in one year in the vacuum of space.
1 light year = 9.4607 × 10¹⁵ meters
1 inch = 0.0254 meters
So:
👉 1 inch = 2.68478 × 10⁻¹⁸ light years
📌 Real-Life Examples
Example 1:
Convert 1 inch
👉 1 × 2.68478 × 10⁻¹⁸ = 2.68478 × 10⁻¹⁸ light years
Example 2:
Convert 1 billion inches
👉 1,000,000,000 × 2.68478 × 10⁻¹⁸ = 2.68478 × 10⁻⁹ light years
Example 3:
Convert 50 billion inches
👉 50,000,000,000 × 2.68478 × 10⁻¹⁸ ≈ 1.3424 × 10⁻⁷ light years
