How to Convert Megabytes to Bytes

MB × 1,000,000 = B
  1. Start with 256 MB
  2. Multiply by 1,000,000: 256 × 1,000,000 = 256,000,000
  3. Result: 256 MB = 256,000,000 B

The same formula works for any value. Multiply by 1,000,000 to go from megabytes to bytes. This uses the decimal (SI) standard. Operating systems may display slightly different values using binary units (1,024 instead of 1,000).
