Byte to Petabyte Converter
Convert bytes to petabytes instantly. Free, bidirectional, and fully in-browser.
1 byte equals 1e-15 petabytes — enter any byte value to convert it to petabytes instantly. This Byte to Petabyte converter is a client-side tool: it applies a single multiplication (PB = B × 1e-15) in your browser, updates the moment you type, and works in both directions — edit either field, or press swap, to convert petabytes back to bytes. A reference table lists common byte values already converted, and nothing you enter is sent to a server.

Why use Byte to Petabyte Converter
Instant, both ways
The result updates as you type, and the swap button flips the conversion to petabyte → byte without reloading.
Exact Digital Storage math
The conversion uses the precise factor (PB = B × 1e-15), so the number matches a manual calculation to the decimal places you choose.
Adjustable precision
A slider sets 0–10 decimal places, and very small or very large results switch to scientific notation instead of rounding to zero.
Private and free
Everything runs locally in your browser — no upload, no account, no limit on conversions.
Common use cases
- Converting a byte measurement to petabytes for a spec, listing, or report.
- Checking byte↔petabyte figures while comparing products, datasets, or documentation.
- Learning the byte-to-petabyte relationship from the worked formula and the common-value table.
Frequently asked questions
How many petabytes are in a byte?
One byte is 1e-15 petabytes. Multiply the byte value by 1e-15 to convert. For example, 10 B = 1e-14 PB.
What is the formula to convert bytes to petabytes?
PB = B × 1e-15. This tool applies it automatically and shows a worked example: 10 B = 1e-14 PB.
Can it convert petabytes back to bytes?
Yes. Press the swap button, or type into the petabyte field, and the tool converts petabytes to bytes using the inverse of the same relationship.
Is the conversion accurate?
It uses the standard digital storage size definition (PB = B × 1e-15), not a rounded approximation, so results are exact to the number of decimal places you select.
Does this work offline and stay private?
Yes. The converter is a browser-side script with no network calls: your values are never uploaded, and once the page has loaded it keeps working without a connection.
