MB to Bytes
Converts megabytes to bytes using both 1000 and 1024 and shows both answers exactly.
One megabyte equals 1,000,000 bytes in the decimal system and 1,048,576 bytes in the binary one. You multiply the number of megabytes by one of these values, and the answer is always a whole number when the megabytes are whole.
You need the exact byte count when a program asks for a size in bytes: an upload limit in the server settings, or the size of a partition or a buffer.
Formula
By 1000: bytes = MB × 1,000,000. By 1024: bytes = MB × 1,048,576.
