"Meters per second" is a proper and wonderful unit for speed, but there's no
answer to that question, because a 'light-year' is not a speed. It's a distance,
defined as the distance that light travels through vacuum in one year.
Speed of light in vacuum . . . 299,792,458 meters per second
Length of 1 light-year . . . . . 9.4605284 × 1015 meters
The speed of light is about 300,000 kilometers per second (3 x 108 meters per second); the distance light travels in a year is called a light-year. It is equivalent to about 9.5 x 1015 meters.
In a vacuum, light always travels at the same speed, approximately 3 x 10^8 meters/second. In a year, there are 31556736 seconds, so light travels 9.5 x 10^15 meters. That unit is called a light year. More details are available at: http://en.wikipedia.org/wiki/Light-year
-Light travels at 299,792,458 meters per second.-There is 31,556,926 seconds in one year.-Light travels 9,460,528,412,464,108 meters in one year and after doing the math, light travels 9,460,528,412,464.108 kilometers in one year.
Exactly 299,792,458 meters per second. Or about 9.461 times 10 to the power 15 meters in a year.
In vacuum, the speed of light is -- 299,792,458 meters per second -- 186,282.397 miles per second. If you were to travel at the speed of light, you could go around the Earth's equator approximately 7.6 times in one second. (Flying in a typical passenger jet, at a ground speed of 500 mph, it would take 4 hours to cross the continental US.)
The speed of light is about 300,000 kilometers per second (3 x 108 meters per second); the distance light travels in a year is called a light-year. It is equivalent to about 9.5 x 1015 meters.
The speed of light is 299,792,485 meters per second so if you travelled at this speed for a whole year that would be a light year.

A "Light Year" is a measure of distance. It equals approximately 9.5 trillion kilometers or 5.9 trillion miles. The Speed of Light (C) is: 299,792,458 meters per second 17,987,547,480 meters per minute 1,079,252,848,800 meters per hour 186,282 miles per second (~ 71/2 times around the Earth in one second) 11,176,920 miles per minute 670,615,200 miles per hour
In space or in air, light covers about 186,000 miles (300,000 km) every second."Light year" is a distance ... the distance light covers in a year, at that speed.
A light-year is exactly 9,460,730,472,580,800 meters.This is about 9.5 × 1015 meters, 9.5 Pm (petametres), or about 9.5 quadrillion meters.It is defined as the distance that light travels in a vacuum in one Julian year. As a Julian year is defined as exactly 365.25 days, and the speed of light in a vacuum is defined as exactly 299,792,458 meters/second, a light year is365.25 days × (24 hours/day) × (60 minutes/hour) × (60 seconds/minute) × 299,792,458 meters/second = 9,460,730,472,580,800 meters.This is not an approximation but an exact number due to the definitions of a Julian year and the speed of light.
Exactly 299,792,458 meters per second. Or about 9.461 times 10 to the power 15 meters in a year.
Light travels approximately 9,460,706,958,078,329 meters in one year.
