• megabytes: A megabyte is usually 1,048,576 bytes (1,024 KB). A phone photo is ~3–5 MB; a song ~5 MB.
• kilobytes: A kilobyte is often 1,024 bytes (binary), but drive makers use 1,000 — the classic "missing space" mystery.
• Storage uses binary: 1 KB = 1,024 B. Drive makers often quote decimal (1 KB = 1,000 B), so real capacity looks smaller.
1 MB = 1024 KB. Use the converter above to compute any value, or multiply MB by 1024.
Yes — conversions use the standard international factors and are rounded to 4 decimals.
