About this tool
This converter uses SI decimal prefixes: 1 KB = 1,000 bytes. Binary kibibytes are not mixed in, so file-size estimates stay consistent.
How it works
Enter a size, pick the source and target units, and copy the result if you need it.
1 KB = 1,000 B
1 MB = 1,000,000 B
Examples
1 GB to MB
1 Ă— 1,000 = 1,000 MB.
FAQ
Is a MB 1,000,000 or 1,048,576 bytes?
Here, 1,000,000 (SI). Drive makers usually use this too.
What about KiB and MiB?
Those are binary units. This tool stays on decimal prefixes for clarity.
