Formula and Step-by-Step

MB × 1,000,000 = B
  1. Start with 646 MB
  2. Multiply by 1,000,000: 646 × 1,000,000 = 646,000,000
  3. Result: 646 MB = 646,000,000 B

Since 1 megabyte equals 1,000,000 bytes, multiply any megabyte value by 1,000,000 to convert. This uses the decimal (SI) standard. Operating systems may display slightly different values using binary units (1,024 instead of 1,000).
