How Many Kilobytes in a Megabyte?
Quick Answer
There are 1,000 kilobytes in a megabyte (MB) using the SI standard, or 1,024 kibibytes in a mebibyte (MiB) using the binary standard.
1 MB = 1,000 KB (SI) or 1 MiB = 1,024 KiB (binary)
Understanding the Conversion
In the SI (decimal) standard, one megabyte (MB) equals exactly 1,000 kilobytes (KB). In the binary standard, one mebibyte (MiB) equals 1,024 kibibytes (KiB). File sizes displayed by operating systems may use either standard depending on the platform.
Formula
1 MB = 1,000 KB (SI) or 1 MiB = 1,024 KiB (binary)
Common Examples
| Description | Value |
|---|---|
| A smartphone photo | About 2-5 MB (2,000-5,000 KB) |
| An MP3 song (4 min) | About 4 MB (4,000 KB) |
| A Word document | About 50-500 KB |
