A light-year is the distance that light travels in a vacuum in one year. Light travels very fast, so this distance is enormous.

While light-years are standard for cosmic distances, converting to centimeters can be useful for specific scientific calculations or educational purposes to grasp the scale.

It's not a conversion you'd use every day, but it's relevant in advanced astronomy and physics for detailed measurements and comparisons.

One light-year is approximately 946,073,047,258,080,000 centimeters.
