How to convert astronomical unit to light-second

Converting astronomical unit to light-second is possible because there is a fixed relationship: since 1 astronomical unit is the same as 499 in ls.

The formula to perform this conversion is:

ls=UA×499,00478mathrm{ls} = mathrm{UA} times 499{,}00478

Learn how to calculate:

  1. Choose the value that is in UA.
  2. Enter that number into the formula.
  3. The conversion is done by multiply by the 499,00478 value.

The final number is the conversion in light-seconds (ls).

Example:

Solving the conversion of 1 UA to ls is easy using the 499,00478 value. Watch the step by step: 1 × 499,00478 = 499.00478. In the end, 1 UA perfectly equals 499.00478 ls.
