Ronnabytes (RB) to Quettabytes (QB) Converter
Convert ronnabytes to quettabytes.
1 RB = 0.001 QB
How to convert RB to QB
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 Quettabyte is 1030 bytes. Divide one by the other and you get the ratio between the two units: 1027 ÷ 1030 = 10−3.
Ronnabyte is the smaller unit, so you divide. One RB is only 0.001 of a QB, which means the decimal point moves 3 places to the left.
These two sit side by side on the ladder (B → KB → MB → GB → TB → PB → EB → ZB → YB → RB → QB), so there is nothing to work out beyond remembering that every step is a factor of 1,000.
The formula
QB = RB ÷ 1,0001 RB = 0.001 QB
Worked example 1: Converting 1 RB
1 RB ÷ 1,000 = 0.001 QBThe decimal point moves 3 places to the left.
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 ÷ 1,000 = 0.0005 QBThe decimal point moves 3 places to the left.
Worked example 3: Converting 12.75 RB
12.75 RB ÷ 1,000 = 0.01275 QBThe decimal point moves 3 places to the left.

The ronnabyte is a new name that exists so future data totals have a label. In quettabytes that is 0.001 QB.
| RB | QB |
|---|---|
| 1 RB | 0.001 QB |
| 2.5 RB | 0.0025 QB |
| 10 RB | 0.01 QB |
| 50 RB | 0.05 QB |
| 100 RB | 0.1 QB |
| 500 RB | 0.5 QB |
| 1,000 RB | 1 QB |
Where RB to QB 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.
Quetta- is the SI prefix for 1030, also adopted in 2022, so a quettabyte is 1,000 ronnabytes. Quettabytes are the top of the official SI ladder. They turn up in unit tables and in explanations of the newest prefixes.
Going from ronnabytes up to quettabytes 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.
RB to QB FAQ
How many quettabytes are in 1 ronnabyte?
One ronnabyte is 0.001 of a quettabyte. It takes 1,000 ronnabytes to make 1 quettabyte.
Is RB to QB 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 QB the gap is wider still.
How do I convert QB to RB?
Go the other way: multiply by 1,000, which moves the decimal point 3 places to the right. The swap button on the converter does it for you.
