They both are a type of Distance.
Each light-year is about 9.5 x 1012 kilometers, so you can multiply by that number.
A meter is defined as the length light travels in 1/299,792,458th of a second. This is because light travels at 299,792.458 kilometers per second.
1 parsec is 3.26 light-years. 100 parsecs is 326 light-years. D(ly) = D(pc) x 3.26

The answer depends on what measure you want it as a fraction of: a metre, kilometre, mile, light year?
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.
A light year is the distance that light travels in a year, so it is a measure of distance, not time. Light travels at about 186,000 miles per second or about 300,000 kilometres per second. There are 31,536,000 seconds in a year. There is about 5,869,713,600,000 miles in a light year or about 9,445,950,434,500 kilometres.
A light year is a measure of distance, not time, and so there's no relation between the two in this case. However one statement that can be said is that 50,000 light years is the distance travelled by light in 50,000 human years.

Uuuh... Yes... =.=
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.
If the two of them are very serious about this marriage relation it can very well be a success.
