About This Conversion
Megabytes to kilobytes multiplies by 1,000 in decimal units. It is the conversion needed when a limit is stated in megabytes but a tool reports or requires kilobytes: upload caps, image size restrictions, form field limits.
Application settings often ask for kilobytes specifically. A 2 MB upload cap is 2,000 KB, and a 25 MB attachment limit is 25,000 KB. Configuration that expects kilobytes and receives megabytes silently applies a limit a thousand times too small.
The binary convention is the catch. Older software and Windows file dialogs treat 1 MB as 1,024 KB, so a limit written as 2 MB may really be 2,048 KB. When a file that looks just under a limit is rejected, or one just over it is accepted, check which convention the tool uses before assuming it is broken.
