How do you convert au to light years?

Answer 1

the light from the sun takes 81/2 minutes to reach earth(=1a.u.).

Light travels 186,000 miles per second. 510 seconds times 186,000=94,860,000.

Earth is on average 94 million miles from the sun.

Light travels 11,160,000 miles in 1 minute, 669,600,000 miles in 1 hour,16,070,400,000 in 1 day and 5,865,696,000,000 miles in one year(1 light year).

Now divide 94,860,000 by 5,865,696,000,000 to get your answer in I believe a number that is in the hundredths (i.e.=.00whatever my calculator cannot handle numbers in the trillions).

Answer 2

Astronomical units are commonly used to express distances within the Solar System. Light-years are commonly used for larger distance - distances to other stars, or other galaxies. Parsecs are also used for large distances.

Answer 3

To convert astronomical units (au) to light years, you can use the conversion factor of 1 au = 1.5813 x 10^-5 light years. Simply multiply the number of astronomical units by this conversion factor to find the equivalent distance in light years.

Answer 4

1 Astronomical Unit = 1.58128588 × 10-5 light years 1 light year = 63 239.6717 Astronomical Units

Answer 5

A light-year is about 63,241.1 astronomical units. You can multiply by that value (or some approximation, like 63,000 AU).

Answer 6

Divide by 63,239.6717.
