To convert megabits to petabytes, divide by 8 then adjust for scale. Since 1 byte = 8 bits, this conversion translates bit-based measurements to the byte-based units used for storage capacity.
Mb measures data in bits—commonly used for memory addressing and low-level data specifications.
PB measures data in bytes—the standard unit for file sizes, storage capacity, and what you see in file explorers. Related: Megabits to Gigabytes.
1 Mb = 1.250000e-10 PB (using SI decimal standard) — or equivalently, 1 PB = 8,000,000,000Mb.

SI Decimal Prefixes: How Mb to PB Is Calculated
Both megabits and petabytes are SI decimal units, so every prefix step is exactly 1,000 and 1 Mb = 1.250000e-10 PB. This is the convention behind advertised link speeds and drive specifications. Because one unit counts bits and the other bytes, the factor also includes a factor of 8.
| Unit | Standard | Prefix step | 1 unit equals |
|---|---|---|---|
| Megabit (Mb) | SI decimal | 1,000 | 1,000,000 bits |
| Petabyte (PB) | SI decimal | 1,000 | 8.000 × 10¹⁵ bits |

FAQs: Megabit to Petabyte Conversion
6 questions Quick answers on converting megabits to petabytes, using the same factors as the converter above.
-
How many petabytes are in 1 megabit?
1 Megabit (Mb) equals 1.250000e-10 Petabytes using the SI decimal standard.
-
How many megabits are in 1 petabyte?
1 PB = 8,000,000,000 Mb
1 Petabyte (PB) equals 8,000,000,000 Megabits.
-
How do I convert megabits to petabytes?
Multiply the megabit value by 1.250000e-10 to get petabytes. For example, 10 Mb = 0.00000000125 PB. To convert back (vice versa), multiply petabytes by 8,000,000,000.
-
Is a megabit bigger than a petabyte?
PB is 8,000,000,000× larger than Mb
No. 1 Mb = 1.250000e-10 PB, so the petabyte is larger — 1 PB = 8,000,000,000 Mb.
-
Does Mb to PB use SI decimal or binary prefixes?
Base 10 (SI): 1,000 per step
Both megabits and petabytes are SI decimal (base 10) units, so each prefix step is exactly 1,000, giving 1 Mb = 1.250000e-10 PB. Because one unit counts bits and the other bytes, the factor also includes a factor of 8. The binary (IEC) versions count in base 2 steps of 1,024 instead.
-
What is Megabit (Mb) commonly used for?
Common uses of the megabit (Mb) include: Internet speeds (Mbps), video streaming bitrates, network bandwidth.
