Bits in a Byte

No matter if it is how many megabytes in a gigabyte, how many kilobytes in a megabytehow many bits in a byte, how many bytes in a megabyte or how many bytes in a kilobyte etc. These are questions that a lot of people have been asking us so we have produced a list for everyone to see.  We have also included a downloadable one HERE.  Only available in Excel format right now.
