Kilobytes (KB) to Megabytes (MB) Converter
The Kilobytes (KB) to Megabytes (MB) Converter turns your Kilobyte (KB) value into Megabytes (MB). Type your storage value below — 1 KB = 0.001 MB, calculated across both decimal (SI) and binary (IEC) standards. This free kilobyte to megabyte calculator doubles as a digital storage converter, file size converter, and data capacity calculator for accurate unit conversion. Also see: Bytes to Exabytes.
Kilobyte (KB)
A kilobyte is 1,000 bytes using the SI decimal standard. Commonly used for small file sizes.

A megabyte is 1,000 kilobytes or 1,000,000 bytes using the SI decimal standard.
View the megabyte data unit pageHow to Convert Kilobytes to Megabytes
To convert kilobytes to megabytes, divide by 1,000 (using SI decimal). Both units measure storage capacity—the difference is scale.
KB: A kilobyte is 1,000 bytes using the SI decimal standard. Commonly used for small file sizes.
MB: A megabyte is 1,000 kilobytes or 1,000,000 bytes using the SI decimal standard.
1 KB = 0.001 MB (using SI decimal standard) — or equivalently, 1 MB = 1,000KB.
KB to MB conversion rate: 1 kilobyte equals 0.001megabytes — the standard kilobyte to megabyte data storage conversion used by this calculator.

KB to MB Conversion Formula
Here's the exact KB to MB formula in copy-paste-ready form — multiply by 0.001 to go from kilobytes to megabytes, or by 1,000 to reverse it — followed by a quick-reference chart of the same conversion.
// Convert KB to MB
MB = KB × 0.001
// Reverse: Convert MB to KB
KB = MB × 1,000

SI Decimal vs Binary: Why Two Different Standards?
When converting kilobytes to megabytes, different tools may give slightly different results. This is because there are two competing standards for measuring digital storage:
| Standard | Base | 1 KB equals | Used By |
|---|---|---|---|
| SI Decimal | 1000 | 1,000 bytes | Hard drive manufacturers, macOS, network speeds |
| Binary (IEC) | 1024 | 1,024 bytes | Windows, Linux (partially), RAM specifications |
Note: Our calculator defaults to SI decimal (base 1000) to match the box label. To match Windows, toggle the standard above the converter.
Want to skip the ambiguity entirely? Kibibyte (KiB) and Mebibyte (MiB) are the IEC binary-only siblings of kilobyte and megabyte — always base 1,024, no dual-standard guessing. See the KiB to MiB converter.
FAQs: Kilobyte to Megabyte Conversion
How many megabytes are in 1 kilobyte?
1 Kilobyte (KB) equals 0.001 Megabytes using the SI decimal standard, or 0.0009765625 MB using the binary (IEC) standard.
How do I convert kilobytes to megabytes?
Multiply the kilobyte value by 0.001 to get megabytes. For example, 10 KB = 0.01 MB.
Is a kilobyte bigger than a megabyte?
No. 1 KB = 0.001 MB, so the megabyte is larger — 1 MB = 1,000 KB.
What is Kilobyte (KB) commonly used for?
Text documents, small images, email attachments, configuration files.
