View the kilobyte data unit pageHow to Convert Mebibytes to Kilobytes
To convert mebibytes (binary/IEC) to kilobytes (decimal/SI), multiply by 1,048.576. Binary units use base 1,024, while decimal units use base 1,000—this creates small differences that accumulate at larger scales.
MiB is a binary (IEC) unit where 1 MiB = 1,024 of the smaller unit. Operating systems like Windows typically display storage using binary calculations.
KB is a decimal (SI) unit where 1 KB = 1,000 of the smaller unit. Storage manufacturers use decimal units, which is why a "1 TB" drive shows less in Windows. Related: Mebibytes to Petabytes.
1 MiB = 1,048.576 KB (using SI decimal standard) — which means there are 1,048.576kilobytes in every mebibyte.

SI Decimal vs Binary: Why MiB to KB Is Not a Round Number
Kilobyte (KB) is an SI decimal unit: each prefix step multiplies by 1,000, so 1 KB = 8,000 bits. Mebibyte (MiB) is an IEC binary unit: each prefix step multiplies by 1,024, so 1 MiB = 8,388,608 bits. Dividing one by the other gives 1,048.576, which is why MiB to KB is not a round number.
| Unit | Standard | Prefix step | 1 unit equals |
|---|---|---|---|
| Mebibyte (MiB) | Binary (IEC) | 1,024 | 8,388,608 bits |
| Kilobyte (KB) | SI decimal | 1,000 | 8,000 bits |
To compare like with like, use MB to KB for SI decimal or MiB to KiB for binary (IEC).

6 questions Quick answers on converting mebibytes to kilobytes, using the same factors as the converter above.
-
How many kilobytes are in 1 mebibyte?
1 MiB = 1,048.576 KB
1 Mebibyte (MiB) equals 1,048.576 Kilobytes using the SI decimal standard.
-
How many mebibytes are in 1 kilobyte?
1 KB = 0.000953674316 MiB
1 Kilobyte (KB) equals 0.000953674316 Mebibytes.
-
How do I convert mebibytes to kilobytes?
MiB × 1,048.576 = KB
Multiply the mebibyte value by 1,048.576 to get kilobytes. For example, 10 MiB = 10,485.76 KB. To convert back (vice versa), multiply kilobytes by 0.000953674316.
-
Is a mebibyte bigger than a kilobyte?
MiB is 1,048.576× larger than KB
Yes. 1 MiB = 1,048.576 KB, so the mebibyte is the larger data storage unit.
-
Why is MiB to KB not a round number?
1 KB = 8,000 bits · 1 MiB = 8,388,608 bits
Kilobyte (KB) is an SI decimal (base 10) unit and Mebibyte (MiB) is a binary IEC (base 2) unit, so their prefixes step by 1,000 and 1,024. That is why 1 MiB = 1,048.576 KB instead of a round number.
-
What is Mebibyte (MiB) commonly used for?
Common uses of the mebibyte (MiB) include: Linux file sizes, RAM specifications, software download sizes.
