A light year, abbreviated ly, is the distance light travels in one year: roughly 9.46 × 1012 kilometres (9.46 petametres, or about 5.88 × 1012 (nearly six trillion) miles). More specifically, a light year is defined as the distance that a photon would travel, in free space and infinitely far away from any gravitational or magnetic fields, in one Julian year (365.25 days of 86400 seconds each).
A megametre (American spelling: megameter, symbol: Mm) is a unit of length equal to 10^6 metres (from the Greek words megas = big and metro = count/measure). Its customary equivalent is 621.37 miles.
