A light year is the distance that light will travel in a vacuum in a year. Nothing can travel that distance in an hour so a lightyear per hour is a meaningless concept of speed. Though impossible to attain, it is a measure of speed while a kilometre is a measure of distance. There is no direct relationship between the two.
1,079,252,850 km or in other words a very very long way
Light year, kilometre, metre, centimetre, millimetre, micrometre, nanometre. And for the old fashioned, light year, mile, furlong, chain, yard, foot, inch, thou. Both systems contain many other units that are used less often.
The distance light travels in a year is called light-year
A light-minute is the distance light travels in a vacuum in one minute's time. The distance of a light-minute is 11,176,943.8 miles or 17,987,547.5 km
They both are a type of Distance.

Each light-year is about 9.5 x 1012 kilometers, so you can multiply by that number.
Because to say a star is 4.3 light-year away easier than saying it's 40,680,000,000,000 kilometers away. Granted you could say it's 40.68 trillion kilometres but that method never really caught on. --- Expressing the conventional units for distance in light-year does not only provide a clear grasp of the idea of the distance that is long long way away, but it is also more convenient when you express the quantity in writing.
A light-minute is a measure of distance. It is the distance light travels in one minute's time. One light-minute is a distance of about 11,176,943.82 miles.
'Light-year' is a unit of a distance. It is the distance for light to travel one year. So it is a great distance.
The distance has been generally presented in Light-years, which is the distance light travels in one-year. The distance to Alpha Centari is 4.7 light-years (alpha Centari is 4.3 light-years distance).
1 light day is a distance.
A light year is the distance light travels in one year and is a measure of distance or length. It equates to about 5.9 trillion miles.
A light year is a measure of distance, not time. A light year is the distance that light will travel in one year. One light second is 186,000 miles. A light year is a measure of distance, not time. A light year is the distance that light will travel in one year. One light second is 186,000 miles.
