How to convert GB to PB
File sizes here use the decimal (SI) system, the same one drive makers and network providers use. In that system 1 Gigabyte is 109 bytes and 1 Petabyte is 1015 bytes. Divide one by the other and you get the ratio between the two units: 109 ÷ 1015 = 10−6.
Gigabyte is the smaller unit, so you divide. One GB is only 0.000001 of a PB, 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.
The formula
PB = GB ÷ 1,000,0001 GB = 0.000001 PB
Worked example 1: Converting 4.7 GB
4.7 GB ÷ 1,000,000 = 0.0000047 PBThe decimal point moves 6 places to the left.
4.7 GB is the capacity of a single-layer DVD.
Worked example 2: Converting 0.5 GB
0.5 GB ÷ 1,000,000 = 5 × 10−7 PBThe decimal point moves 6 places to the left.
Worked example 3: Converting 12.75 GB
12.75 GB ÷ 1,000,000 = 0.00001275 PBThe decimal point moves 6 places to the left.

Where GB to PB comes up
A gigabyte is 1,000 megabytes, about 250 photos at 4 MB each. Gigabytes are the language of phone storage, RAM, mobile data plans, game installs and USB sticks.
A petabyte is 1,000 terabytes, or a million gigabytes. Petabytes belong to data centres, research archives, big analytics warehouses and the storage side of large cloud services.
Going from gigabytes up to petabytes 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.
