What is the size of the universe in feet?

Answer 1

2,855,601,061,277,669,291,338,582,677.165 feet.
OR
#2.855 " x " 10^27" feet"#

You may not realize the scope of the universe, but

The circumference of the observable universe is 92 billion light years, or 92,000,000,000. A light year is defined as the distance traveled by light in a year, and light travels at about 186 thousand miles per second, or 983,781,341.35 feet per second, or nearly 984 million feet in just one second. When we multiply this number by 60 seconds, 60 minutes, 24 hours, and 365 days to get to a year, it becomes 31,039,141,970,409,448.819, or 31 quadrillion feet. This is one light year. When we multiply that by the universe's diameter, we obtain:

2,855,601,061,277,669,291,338,582,677.165 feet. OR if you prefer scientific notation: #2.855 " x " 10^27" feet"#
