Sizes Explained

Using the metric system 1,000 bytes would be a k, or kilobyte, but in the computer industry a k is equal to 1024 bytes. That means each of the below metric designations are approximate for computer terminology. Some medical computers currently have storage measured in petabytes. Even as devices have shrunk in size, demand for storage has increased in inverse proportion.


kilo = thousand
mega = million
giga = billion (There are 1,024 GB in 1 TB.)
tera = trillion (There are 1,498 CD discs in 1 TB)
peta = quadrillion (A human brain can store about 2.5 PB of data)
exa =
quintillion (Almost 11 million 4K movies can fit in 1 EB)
zetta =
sextillion (1,180,591,620,717,411,303,424)
yotta =
septillion
