What are the standard units of apparent brightness?
The apparent brightness is assigned a unit called "magnitude", abbreviated "m". Lower numbers mean a brighter star. It is a logarithmic scale, such that every 5 numbers represent a factor of 100; a difference of 1m corresponds, approximately, to a factor of 2.5.
