About Converting Petabits to Exabits
Petabit and Exabit are everyday digital-storage units, used for everything from file sizes and app downloads to storage device capacity and mobile data allowances. Specifically: Petabit digital storage unit, and exabit digital storage unit.
Formula
exabits = petabits × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 petabit equals 1e+15 base units, and 1 exabit equals 1e+18 base units, so dividing one by the other gives the direct petabit-to-exabit factor of 0.001.
Simple example
1 Pb × 0.001 = 0.001 Eb
1 petabit = 0.001 exabits.
Real-world example
500 Pb × 0.001 = 0.5 Eb
500 petabits = 0.5 exabits.
