What is the size of the observable universe in feet?

Answer 1

Its not really meaningful to express the size of the universe in feet. But its 93 billion light years in size (Wiki).

This indicates that it would take 93 billion years for light to travel this distance if a laser beam were fired from the edge of the known universe in the opposite direction.

It makes no sense to express the size of the universe in feet because feet are more useful for measuring things like the size of a house or a city block. Miles or kilometers are a better unit of measurement for larger objects like the distance between cities or towns. Light years are the best unit of measurement for really big objects like the universe!

With a diameter of about 93 billion light-years, or 5.5 × 10^23 feet, the observable universe is quite large.

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.
