A light year is the distance light travels in one year. Very roughly 6 trillion miles.
When measuring distances it is important to choose a unit suitable for the distance being measured.
For instance you would not measure the distance between two cities in inches you would choose miles or kilometres.
Because of the truly huge distances involved when measuring astronomical objects large units were needed. So the light year is used, among other things.

How many months are there in a light year?
A light year is a measure of distance. A light year is about 9,460,000,000,000 km, the distance light travels in a vacuum in one Earth year. It has nothing to do with weeks, months, days, etc. or any other of our calendar measurements of time.
Which unit of measurement uses the distance light travels in one year 9470000000000?
The distance light travels in one year is called a light-year. To get the number 9,470,000,000,000, the unit used is the kilometer.
An astronmoical unit is a larger distance unit than a light year?
This statement is incorrect. An astronomical unit (AU) is a unit of distance equal to the average distance between the Earth and the Sun, approximately 93 million miles. A light year, on the other hand, is the distance that light travels in one year, about 5.88 trillion miles. So, a light year is a much larger distance unit than an astronomical unit.
Which unit of measurement represents the distance light travels in one year light-year or parsec?
"light-year"
What is the relation between light year and astronomical unit?
The astronomical unit is the average distance from the earth to the sun, and is 149 598 000 kilometres. A light year is the distance light will travel in a year, the speed of light is just under 300 000 kilometres per second, so light travels one astronomical unit in just over eight minutes. A light year is 9.46x1012 kilometres, or 63239.67 astronomical units.
Which of the is not a unit of time leap year or light year?
A light-year is a unit of distance, not a unit of time.
How old is mira the star in light years?
"Light-year" is NOT a unit of time. It is a unit of length or distance - the distance light travels in a year.
Does a calendar year equal a light year?
No. A light year is a unit of distance, not time. It is the distance light travels in a year.
How many hours is a light year?
This is an impossible conversion to make. A hour is a unit of time. A light year is a unit of distance, specifically, it is the distance light travels in a year.
Is a light year a unit of time True or false?
False the light year is not a unit of time it is a unit of distance true.
Is a light year a unit of a distance or a unit of a time?
Both
Is the sun measured in light years?
'Light-year' is a unit of a distance. It is the distance for light to travel one year. So it is a great distance.
How is the unit light-year is a measured?
Distance
