Explanation:
Detailed explanation-1: -One megabyte is about 1 million bytes (or about 1000 kilobytes).
Detailed explanation-2: -In the International System of Units (SI) the prefix kilo means 1000 (103); therefore, one kilobyte is 1000 bytes. The unit symbol is kB.
Detailed explanation-3: -In digital units of measurement, 1 MB is equal to 1024 Kilo Bytes or KB.
Detailed explanation-4: -In the metric system, mega is a prefix for 1, 000, 000, or 106. So in some cases, a megabyte is defined as 1, 000, 000 bytes. But because computers work in binary, computer scientists usually define a megabyte as 220, or 1, 048, 576 bytes. This works out to 1, 024 kilobytes.
