One megalight-year, abbreviated "Mly", is one million light-years, or 306,601 parsecs. Megalight-years are typically used to measure distances between neighboring galaxies and galaxy clusters.
A light-second is a unit of length. It is defined as the distance light travels in an absolute vacuum in one second or 299,792,458 meters. Note that this value is considered exact, since the meter is actually (as of 1983) defined in terms of the light second. It is just over 186,282 miles and almost 109 feet.
