Terabytes (TB) to Exabytes (EB) Converter

File sizes here use the decimal (SI) system, the same one drive makers and network providers use. In that system 1 Terabyte is 10¹² bytes and 1 Exabyte is 10¹⁸ bytes. Divide one by the other and you get the ratio between the two units: 10¹² ÷ 10¹⁸ = 10⁻⁶.

Terabyte is the smaller unit, so you divide. One TB is only 0.000001 of a EB, which means the decimal point moves 6 places to the left.

On the ladder (B → KB → MB → GB → TB → PB → EB → ZB → YB → RB → QB) these two are 2 steps apart. Every step is a factor of 1,000, so 2 steps means 1,000 multiplied by itself 2 times, which is 10⁶.

A terabyte is 1,000 gigabytes, about 250,000 photos at 4 MB each. Terabytes are how consumer SSDs, external drives, home NAS boxes and cloud storage plans are sold.

An exabyte is 1,000 petabytes, or a billion gigabytes. Exabytes describe traffic across whole networks, national-scale archives and industry forecasts, not any single file or drive.

Going from terabytes up to exabytes always gives a smaller number, because you are counting in bigger chunks. People do it to make a long number readable, or to compare a file with the size of a drive or a plan.
