3 AU = 4.7437e-5 ly
Full precision:0.000047437 ly
Step-by-Step Solution
To convert 3 astronomical units to light years, we divide by 63241.98 because one light year equals exactly 63241.98 astronomical units.
1 light year = 63241.98 astronomical units
Since there are 63241.98 astronomical units in every light year, we divide our value by this factor:
3 ÷ 63241.98 = 4.7437e-5 light years
So 3 astronomical units = 4.7437e-5 light years.
Quick check: 4.7437e-5 × 63241.98 = 3 astronomical units
