Formula and Step-by-Step

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

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