How to convert Megabytes to Kilobytes
To convert megabytes to kilobytes, multiply by 1,024. One megabyte equals 1,024 KB, and one kilobyte equals 0.000976562 MB.
- Take the value in megabytes — for example 3 MB.
- Multiply by 1,024 (the number of kilobytes in one megabyte).
- 3 × 1,024 = 3,072 KB.
Quick mental estimate: Multiply the number of megabytes by 1,024 — that is exact.

About converting Megabytes to Kilobytes
Megabytes (MB) and Kilobytes (KB) are both units of data storage. The exact factor is 1 MB = 1,024 KB, so multiply by 1,024 to go from megabytes to kilobytes (or divide to go back).
The conversion runs entirely in your browser. Need the reverse? Use the Kilobytes to Megabytes converter, or the full unit converter for every unit at once.
Binary vs decimal: why your drive looks smaller
Windows and RAM reports count in powers of 1,024 (binary, sometimes written KiB/MiB/GiB); drive makers, macOS and mobile carriers count in powers of 1,000 (decimal). Same bytes, two answers:
| Megabytes | Kilobytes (binary · Windows) | Kilobytes (decimal · on the box) |
|---|---|---|
| 1 MB | 1,024 KB | 1,000 KB |
| 2 MB | 2,048 KB | 2,000 KB |
| 4 MB | 4,096 KB | 4,000 KB |
| 5 MB | 5,120 KB | 5,000 KB |
| 8 MB | 8,192 KB | 8,000 KB |
| 10 MB | 10,240 KB | 10,000 KB |
| 16 MB | 16,384 KB | 16,000 KB |
| 20 MB | 20,480 KB | 20,000 KB |
| 32 MB | 32,768 KB | 32,000 KB |
| 50 MB | 51,200 KB | 50,000 KB |
Example: a “1 TB” drive holds 10¹² bytes, which Windows shows as about 931 GB.
Real-world data storage in megabytes and kilobytes
| Example | Megabytes | Kilobytes |
|---|---|---|
| A page of plain text | ≈ 0.00190735 MB | ≈ 1.953125 KB |
| A 4-minute MP3 at 128 kbps | 3.662109 MB | 3,750 KB |
| A CD | 700 MB | 716,800 KB |
| A single-layer DVD (4.7 GB) | 4,482.269 MB | 4,589,844 KB |
| A 50 GB dual-layer Blu-ray | 47,683.72 MB | 48,828,125 KB |
“≈” marks typical values; the rest are defined or measured figures.
The units
Here, 1,024 KB = 1,048,576 bytes (MiB). Decimal megabyte = 1,000,000 bytes.
Used for: Photos, songs, app downloads.
Here, 1,024 bytes (binary, also written KiB). Decimal kilobyte = 1,000 bytes.
Used for: Small files, documents.
This page uses binary units (1 KB = 1,024 bytes), which is how Windows and most RAM reports count. Storage makers and macOS use decimal units (1 kB = 1,000 bytes), so both are shown below.
