Formula & Explanation

Formula

Kilometers = Light Years × 9.461e+12

Step-by-step explanation

One light-year is the distance light travels in a vacuum in one Julian year. This distance is approximately 9.461 trillion kilometers. To convert light-years to kilometers, you multiply the number of light-years by this enormous value. For example, Proxima Centauri, the nearest star to our Sun, is about 4.24 light-years away, which is 4.24 × 9.461e+12 ≈ 40.1 trillion km.

FAQ

What is a light-year?

A light-year is a unit of astronomical distance. It's not a unit of time, but the distance that light travels in a vacuum in one Julian year (365.25 days).

Publish distances clearly

For outreach or papers, include both the light-year figure and the kilometers in scientific notation. Provide a relatable comparison (e.g., Earth–Sun distance) to improve comprehension.

  • Include uncertainty and method (parallax, redshift, standard candle) where applicable.
  • Avoid mixing significant figures from different sources; round consistently.
  • Link to related units like parsec and AU for context.
