As the quota system uses the term, a block is 512b -- this unit is also called a sector in some situations, but it's basically the same thing. It reflects the size of the underlying sector structures within the filesystem. Most applications that deal in file sizes can deal in units of blocks, (eg. the -s argument to newfs(8) takes an argument in units of sectors or blocks, although just to be confusing, newfs(8) also uses 'block-size' with a different meaning) and in some of the older ones blocks are the default measure. However, more commonly used applications (like df(1)) or more recently written ones either default to reporting in more familiar units -- b, kb, Mb -- or have mechanisms for changing to those units.
