# How many meters are in a lightyear?

## Question:

How many meters are in a lightyear?

There are approximately 9.5x1015 meters in a light year.

One light year is the distance that light travels in a vacuum in one year. The speed of light is 3x108 m/s.

One year has 365x24x60x60 seconds.

So, in one year, light will travel (3x108) x (365x24x60x60) meters = (3x108) x 31,536,000 m = 94608x1011 m = 9.5x1015 m

Therefore, 1 light year is approximately 9.5x1015 m.
