How would you express four trillion bytes?

Four trillion bytes can be expressed as 4 terabytes (TB), since one terabyte is equivalent to one trillion bytes. This can also be represented in smaller units, such as 4,000 gigabytes (GB), since one terabyte equals 1,000 gigabytes. Alternatively, it could be expressed as approximately 4,000,000 megabytes (MB) for even finer granularity.
