Kilobytes to megabytes is common for upload limits on job and exam forms (which often say "under 200 KB"), image sizes and email attachments. Using decimal units, 1 MB = 1000 KB. Some websites and older software count 1 MB as 1024 KB; the difference is only 2.4%, so a file of 990 KB is safely under a 1 MB limit either way.
