Convert yottabytes to petabytes.
1 YB = 1,000,000,000 PB
How to convert YB to PB
File sizes here use the decimal (SI) system, the same one drive makers and network providers use. In that system 1 Yottabyte is 1024 bytes and 1 Petabyte is 1015 bytes. Divide one by the other and you get the ratio between the two units: 1024 ÷ 1015 = 109.
Yottabyte is the bigger unit, so you multiply. Every YB holds 1,000,000,000 PB, which means the decimal point moves 9 places to the right.
On the ladder (B → KB → MB → GB → TB → PB → EB → ZB → YB → RB → QB) these two are 3 steps apart. Every step is a factor of 1,000, so 3 steps means 1,000 multiplied by itself 3 times, which is 109.
The formula
PB = YB × 1,000,000,0001 YB = 1,000,000,000 PB
Worked example 1: Converting 1 YB
1 YB × 1,000,000,000 = 1,000,000,000 PBThe decimal point moves 9 places to the right.
No storage system with published figures reaches a yottabyte yet.
Worked example 2: Converting 0.5 YB
0.5 YB × 1,000,000,000 = 500,000,000 PBThe decimal point moves 9 places to the right.
Worked example 3: Converting 12.75 YB
12.75 YB × 1,000,000,000 = 12,750,000,000 PBThe decimal point moves 9 places to the right.

Where YB to PB comes up
A yottabyte is 1,000 zettabytes, which is 1024 bytes. Yottabytes are mostly a textbook and forecast unit. You meet them in articles about how large data totals could grow.
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 yottabytes down to petabytes always gives a bigger number, because the unit you land on is smaller. It is the usual direction when a limit or a form asks for a smaller unit than the one you have in mind.
YB to PB FAQ
How many petabytes are in 1 yottabyte?
There are 1,000,000,000 petabytes in 1 yottabyte, so 1 YB = 1,000,000,000 PB.
Is YB to PB decimal or binary?
This page is decimal (SI), where 1 KB = 1,000 B. Operating systems often count in powers of 1,024 and still print KB, MB or GB, when they really mean KiB, MiB and GiB. At YB the two systems differ by about 20.9%.
How do I convert PB to YB?
Go the other way: divide by 1,000,000,000, which moves the decimal point 9 places to the left. The swap button on the converter does it for you.
