Ronnabytes (RB) to Petabytes (PB) Converter
Convert ronnabytes to petabytes.
1 RB = 1,000,000,000,000 PB
How to convert RB to PB
File sizes here use the decimal (SI) system, the same one drive makers and network providers use. In that system 1 Ronnabyte is 1027 bytes and 1 Petabyte is 1015 bytes. Divide one by the other and you get the ratio between the two units: 1027 ÷ 1015 = 1012.
Ronnabyte is the bigger unit, so you multiply. Every RB holds 1012 PB, which means the decimal point moves 12 places to the right.
On the ladder (B → KB → MB → GB → TB → PB → EB → ZB → YB → RB → QB) these two are 4 steps apart. Every step is a factor of 1,000, so 4 steps means 1,000 multiplied by itself 4 times, which is 1012.
The formula
PB = RB × 10121 RB = 1,000,000,000,000 PB1012 means 1 followed by 12 zeros
Worked example 1: Converting 1 RB
1 RB × 1012 = 1,000,000,000,000 PBThe decimal point moves 12 places to the right.
The ronnabyte is a new name that exists so future data totals have a label.
Worked example 2: Converting 0.5 RB
0.5 RB × 1012 = 500,000,000,000 PBThe decimal point moves 12 places to the right.
Worked example 3: Converting 12.75 RB
12.75 RB × 1012 = 12,750,000,000,000 PBThe decimal point moves 12 places to the right.

Where RB to PB comes up
Ronna- is the SI prefix for 1027, adopted in November 2022, so a ronnabyte is 1,000 yottabytes. Ronnabytes are new and mostly theoretical. You will see them in unit tables and in pieces about how big future data totals might get.
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 ronnabytes 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.
RB to PB FAQ
How many petabytes are in 1 ronnabyte?
There are 1012 petabytes in 1 ronnabyte, so 1 RB = 1012 PB.
Is RB 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 RB the gap is wider still.
How do I convert PB to RB?
Go the other way: divide by 1012, which moves the decimal point 12 places to the left. The swap button on the converter does it for you.
