rd
AU
640 rd = 2.1515e-8 AU
Full precision:2.15e-8 AU
Step-by-Step Solution
To convert 640 rods to astronomical units, we divide by 2.9746e+10 because one astronomical unit equals exactly 2.9746e+10 rods.
1 astronomical unit = 2.9746e+10 rods
Since there are 2.9746e+10 rods in every astronomical unit, we divide our value by this factor:
640 ÷ 2.9746e+10 = 2.1515e-8 astronomical units
So 640 rods = 2.1515e-8 astronomical units.
Quick check: 2.1515e-8 × 2.9746e+10 = 640 rods
