Size of the Observable Universe = 5.440 x #10^23# miles

Explanation:

The Entire Universe as we see it is roughly 46.3 billion Light-years in any direction. SO, hypothetically the radius of the universe is about 46.3 billion Light-years.

1 Light-year = 9.4 x #10^12# km

46.3 x #10^9# light-years = 46.3 x #10^9# x 9.4 x #10^12# km

46.3 Billion Light-years = 4.3522 x #10^23# km

1 mile = 1.6 km

1 km = 1 / 1.6 miles

1 km = 0.625 miles

4.3522 x #10^23# km = 0.625 x 4.3522 x #10^23# miles

Radius of the Observable Universe = 2.720 x #10^23# miles

Size of the Observable universe = Radius * 2

Size of the Observable Universe = 5.440 x #10^23# miles
