How Many Bytes in a Megabyte?
クイックアンサー
There are 1,048,576 bytes in a megabyte (binary) or 1,000,000 bytes (decimal).
1 MB (binary) = 2²⁰ = 1,048,576 bytes
変換の理解
In computing, 1 megabyte (MB) = 2²⁰ = 1,048,576 bytes (binary/IEC definition). Hard drive manufacturers use the decimal definition (1 MB = 1,000,000 bytes), which is why a drive's labeled capacity appears smaller than reported by an OS.
