If the span of the universe was converted from light years to miles, what would it measure?

Answer 1

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

Since the observed radius of the entire universe is approximately 46.3 billion light-years in all directions, the radius of the universe is approximately 46.3 billion light-years.

9.4 x 10^12 km is one light-year.

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

One mile is equivalent to 1.6 kilometers.

One kilometer is equal to one / 1.6 miles.

One kilometer is equivalent to 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

Radius * 2 is the size of the observable universe.

The observable universe is 5.440 x 10^23 miles in size.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
