How far exactly is a light-year? Light travels 186,000 miles per second. There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 365 days in a year. Multiply these together to get 31,500,000 seconds in a year. Multiply that times 186,000 miles per second and you get 5,850,000,000,000 miles (thats approx. 6 trillion miles.)

Wow... you are asking me to quote a big number...
Well, light travels at 186,000 miles per second.
Times 60 seconds per minute
Times 60 minutes per hour
Times 24 hours per day
Times 365 days per year.
60 x 60 x 24 x 365 = 31,536,000 = 3.156 X 10^7
times 186,000
= 3.156 x 10^7 X 1.86 X 10^5 = 5.870 x 10^12 miles
or
5,870,000,000,000 Miles = 1 Light Year

The speed of light is approximately 186,282.397 miles per second, or 670,616,629.384 miles per hour, or almost one foot per nanosecond.
You cant measure light years like a ruler...In 1 year light would travel 5,874,601,673,403.84 miles

one light year in miles is 9,500,000,000,000 kilometers.
a kilometer is equal to .62 miles
so that makes a light year equal to 5,903,024,500,000 miles

5,865,696,000,000
To be extremely precise, a year has 365.25 days, making a light year approximately 5,869,713,600,000 miles in length.
