9.461*1012 kilometres, approximately.
Lightyear isn't about time, it's distance. One lightyear is ten trillion kilometers.
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.
One lightyear is the distance that light travels in one year, which is about 5.88 trillion miles (9.46 trillion kilometers).
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.
1 light year = 9.46*1012 km or 9.46 trillion km (approx)
Approx 3.1 *1016 or 31 quadrillion.
1 lightyear = 9.46 × 1015 metres
one lightyear is equal to 5.87849981 × 1012 miles (thats 5 trillion, 878 billion, 499 million, 81 thousand miles).
There are many places one can purchase a talking Buzz Lightyear toy. One can purchase them from Amazon, ebay, Toys R Us, Target, Argos or the Disney Store.
A lightyear is a unit of distance, not time. It represents the distance that light can travel in one year, which is about 5.88 trillion miles.
Light can travel about 6 trillion miles in a year, so that distance is called a light-year.
