MB to KB
Converts megabytes to kilobytes using both 1000 and 1024 and shows both answers exactly.
One megabyte holds 1,000 kilobytes by the decimal rule and 1,024 by the binary rule. One and a half megabytes comes out as 1,500 KB or 1,536 KB, depending on which rule you use.
If you need the size for Windows or a school problem, use the "By 1,024" column. For a website or a product listing, use "By 1,000".
Formula
By 1,000: KB = MB × 1,000. By 1,024: KB = MB × 1,024.
