1 light year = 9,460,730,472,580.8 km or 63,239.7263 Astronomical Units (AU).
No. A light year is about 63,000 AU.

One light year is equal to: 0.307 pc (parsecs) 63241 AU 9.461×1012 km 9.461×1015 meters 5.879×1012 miles
No. A light year is much larger than an AU, roughly 63,000 AU.
A light year is much bigger, an AU is only about 8 light minutes.1 light year = 63,240 AU
No. 150 million km is the distance from Earth to Sun, and this distance is called an AU (astronomical unit). Light travels this distance in about 8 minutes.A light-year is the distance traveled by light in a year, which of course is much more than the distance traveled in 8 minutes. A light-year is approximately 9.461 x 10 to the power 12 km.
Actually, "astronauts" usually don't. They measure distances mostly in km. The furthest from Earth any astronaut has ever been is about 400,000 km, which is still a manageable number in km. Astronomers don't either, for the most part; they tend to use either AU (for in-system distances) or parsecs for interstellar distances. When light-years are used, it's generally because the distances involved are too large for km or AU. 1 light year is about 9,500,000,000,000 km, so you can see how much of a difference that makes. 1 light year is only about 63,200 AU, but that still adds up pretty quickly.
1 light-hour = 7.2 AU (rounded) 1 light-hour is approximately 1.08×109 km, while 1 AU is approximately 1.5 x 108 km (149,597,870,700 m).
9 AU = 1,346,380,843 km.9 AU = 1,346,380,843 km.9 AU = 1,346,380,843 km.9 AU = 1,346,380,843 km.
