How Many Bytes in a Kilobyte?
クイックアンサー
There are 1,000 bytes in a kilobyte (KB) using the SI standard, or 1,024 bytes in a kibibyte (KiB) using the binary standard.
1 KB = 1,000 bytes (SI) or 1 KiB = 1,024 bytes (binary)
変換の理解
In the SI (decimal) standard, one kilobyte (KB) equals exactly 1,000 bytes. In the binary standard used by operating systems and memory, one kibibyte (KiB) equals 1,024 bytes (2^10). This discrepancy is why a drive marketed as 500 GB appears as about 465 GiB in your computer.
