Question 169527
                  AU   | Parsec   | Light Year
One AU =         |  1  |4.85*10^-6| (1.58)*10^-5 |
One Parsec =     |20619|   1      |    3.26      |
One Light Year = |63291| 0.307    |      1       |
.
.307/1=P/1.58*10^-5
P=.307*1.58*10^-5
=4.85*10^-6
.
(1.58)*10^-5 /1=1/A
A=1/1.58*10^-5
=6.33*10^-6
.
A/1=1/4.85*10^-5
=20619
.
L/1=1/.307
=3.26
