How to Convert KB to MB
1 MB = 1,024 KB (binary) or 1,000 KB (decimal). Divide KB by 1,024 (or 1,000) to get MB. So 5,120 KB = 5 MB binary. Most software uses binary, so a 5 MB attachment is technically 5,120 KB by file system measurement.
Useful for understanding email attachment limits, image file sizes, and document storage. A typical email-friendly image is 50-500 KB = 0.05-0.5 MB. A pdf document averages 200 KB - 2 MB depending on content. Email providers typically cap attachments at 25 MB = 25,600 KB.

Frequently Asked Questions
What's a typical photo file size?
JPEG from phone camera: 2-5 MB = 2,048-5,120 KB. RAW files: 10-50 MB. Compressed for web: 50-500 KB. Compressed for email: under 1 MB usually fine. Compression matters - same photo can range 100x in file size depending on compression settings.
Why do file sizes round oddly?
Binary vs decimal interpretation differences. A 'truly 1 MB' file (1,000,000 bytes decimal) shows as 0.95 MB binary. A 'truly 1 MiB' file (1,048,576 bytes binary) shows as 1.05 MB decimal. Round numbers in one system are awkward in the other.
