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

- 2
Type the value you want to convert into the Petabyte field.

- 4
Use the decimal-places slider for more or less precision, or press swap to convert bytes to petabytes.
Why use Petabyte to Byte Converter
Instant, both ways
The result updates as you type, and the swap button flips the conversion to byte → petabyte without reloading.
Exact Digital Storage math
The conversion uses the precise factor (B = PB × 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 petabyte measurement to bytes for a spec, listing, or report.
- Checking petabyte↔byte figures while comparing products, datasets, or documentation.
- Learning the petabyte-to-byte relationship from the worked formula and the common-value table.
Frequently asked questions
How many bytes are in a petabyte?
One petabyte is 1e+15 bytes. Multiply the petabyte value by 1e+15 to convert. For example, 10 PB = 1e+16 B.
What is the formula to convert petabytes to bytes?
B = PB × 1e+15. This tool applies it automatically and shows a worked example: 10 PB = 1e+16 B.
Can it convert bytes back to petabytes?
Yes. Press the swap button, or type into the byte field, and the tool converts bytes to petabytes using the inverse of the same relationship.
Is the conversion accurate?
It uses the standard digital storage size definition (B = PB × 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.
