A lot. 5,878,625,373,184 or around 6 trillion miles to a light year.
A lightyear is the distance that light can travel in one year.
Light can travel about 6 trillion miles in a year, so that distance is called a light-year.
22,116,326,410,348,823,000,000,000,000. That's 22 octillion. I took the exact number of miles in a light-year (5,878,499,810,000), squared it to get square miles, and multiplied by 640 for acres per sq mile.
There are approximately 9.46 trillion kilometers in a lightyear. To convert this to millimeters, 1 kilometer is equal to 1,000,000 millimeters. Therefore, there are about 9.46 x 10^18 millimeters in a lightyear.
A lightyear is a unit of distance and not time. It's the distance light travels in a year, roughly equal to 5.88 trillion miles or 9.46 trillion kilometers. Converting that to inches would result in an extremely large number that is not practically useful.
Light can travel about 5.88 trillion miles in one lightyear.
one lightyear is equal to 5.87849981 × 1012 miles (thats 5 trillion, 878 billion, 499 million, 81 thousand miles).
It is 6,000,000,000,000 miles long
1 lightyear is equal to approximately 16.098 billion miles when compared with the number of days.
Roughly 5,868,700,000,000 miles. (rounded)
A lightyear is the distance that light can travel in one year.
Fifty light years in miles: Over 300 trillion.
Light can travel about 6 trillion miles in a year, so that distance is called a light-year.
