No, there are about 63000 astronomical units in a light year.

Explanation:

An astronomical unit - the average distance between the Earth and the Sun - is approximately 500 light seconds.

There are 86400 seconds in a day and approximately 365.25 days in a year, Hence the number of astronomical units in one light year is approximately:

(365.25 * 86400)/500 ~~ 63000
