KB to MB
Converts kilobytes to megabytes using both 1000 and 1024 and shows both answers exactly.
Kilobytes convert to megabytes by dividing by 1,000 or by 1,024. A 2048 KB file is exactly 2 MB under the binary rule and 2.048 MB under the decimal rule.
Windows shows file sizes using 1,024, while drive manufacturers and macOS use 1,000. When a number from a file description doesn't match File Explorer, this is usually why.
Formula
Using 1,000: MB = KB ÷ 1,000. Using 1,024: MB = KB ÷ 1,024.
Precomputed values
| Kilobytes | Using 1,000 | Using 1,024 |
|---|---|---|
| 1 | 0.001 MB | ≈ 0.000 976 563 MiB |
| 100 | 0.1 MB | ≈ 0.097 656 3 MiB |
| 512 | 0.512 MB | 0.5 MiB |
| 1,000 | 1 MB | ≈ 0.976 563 MiB |
| 1,024 | 1.024 MB | 1 MiB |
| 2,048 | 2.048 MB | 2 MiB |
| 5,000 | 5 MB | ≈ 4.88281 MiB |
| 10,240 | 10.24 MB | 10 MiB |
