The factor used here is the defined value: 1 MB = 1000 KB. Results are rounded to six significant digits for readability, so for high-precision work use the full factor. This converter uses decimal (SI) units — 1 MB = 1,000 KB — matching drive labels and macOS. Windows Explorer reports binary mebibytes (1 MiB = 1,024 KiB), so the same file shows a slightly smaller number there. This converter uses decimal (SI) units — 1 KB = 1,000 bytes — the convention storage makers and most operating systems use. The binary kibibyte (KiB) is 1,024 bytes.
Every conversion runs 100% in your browser — zero files uploaded, ever.
