How to Convert Byte to Megabyte

Formula with a worked example (binary (1024))

To convert byte (B) to megabyte (MB), use this formula:

MB = Bytes ÷ 1,048,576 (binary) or Bytes ÷ 1,000,000 (decimal)

Example: Convert 5,242,880 B to MB (binary (1024))

5,242,880 B = 5 MB

To convert back, use: Bytes = MB × 1,048,576 (binary) or MB × 1,000,000 (decimal)
