A light-year is about 9,461,000,000,000 km.
There are approximately 9.46 trillion kilometers in a lightyear. To convert this to millimeters, 1 kilometer is equal to 1,000,000 millimeters. Therefore, there are about 9.46 x 10^18 millimeters in a lightyear.
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.
5 kilometers are 5000 meters.
2 kilometers equals 200 000 centimeters.
Two kilometers equals 2000 meters.
9.461*1012 kilometres, approximately.

Lightyear isn't about time, it's distance. One lightyear is ten trillion kilometers.
.0007 kilometers equals 700 milimeters.
Three feet equals 0.0009144 kilometers.
250 millimeters equals .000250 kilometers
