A light year is the distance which light will travel in a vacuum. Light travels at 299,792,458 m/s in a vacuum, one year is 31557600s (on average taking into account leap years) so 1 light year is 9.46073x10^15m or 9 460 730 473 000 km

The distance light travels in a year is called light-year
A light-year is the distance light can travel in one year. Light travels at 186,000 miles per second. Multiply that by 3600 seconds in an hour and then by 24 hours in a day and 365 days in a year and you will get the distance in one light-year.A light year is defined as 9,460,730,472,580,800 meters exactly, derivedfrom the distance that light travels in vacuum in one Julian year.
No. A light-year is a measurement. A light year is a distance measurement based on how far light travels in a year.
Only one. Because Light year is a messure of distance not of time. Light year is the distance travelled by light in one year.
you cant light years refer to the distance light can travel in 1 year 1 Light Year = 5878625373183.61 Miles
A light-year is the distance traveled by light in one year. Note that light moves at a speed of about 300,000 km/second.A light-year is defined to have EXACTLY 9,460,730,472,580,800 meters (or approximately 9.5 quadrillion meters).
If you refer to the units, both the light-year and the parsec are often used. A light-year is the distance light travels in a year; about 9.5 x 1012 kilometers (9.5 million million kilometers). A parsec is about 3.26 light-years.
The term used to refer to a quantum of light is a photon.

"Lights" is plural. The singular is "light." As a noun, the word "light" can refer to something you turn on to brighten a room, or it can refer to brightness in the sky. Here is an example of the plural: When we had a hurricane last year, the lights went out everywhere on our street.

The tire pressure monitoring system varies on Pontiac Grand Prix depending on the year of the car as some years do not have the TPMS. To reset the TPMS light, refer to the manual for your car.
A light-year is the distance light travels in a year. "Student minute" is not a standard unit of length or distance; perhaps somebody used it to refer to how far a student walks in a minute. Please note that different students will walk at different speeds. If this is what was meant, then you have two different units of length defined as a speed multipled by a time.
