一个 kbkilobit,千比特) 表示 1,000 (103) 比特,而不是普遍被認為的1,024比特。 “kilobit”或千比特这一术语通常以缩略式kbkbit表示。注意kilobit(千比特)的缩写为kb,不要与术语kilobyte(千字节,缩写为kB或KB,其中的“B”是大写的)相混淆。 尽管它的前缀“kilo-(千)”常和字节(Bytes)誤用為 1,024 Byte,但kb 的十进制定义(1kbps=1,000bps)在电信传送速率的相关文字中仍被统一使用。

“kbps” “kb/s”[1]或“kbit/s”用于表示数据传输速率(码率),意为“千比特每秒”。 例如,“56 kbit/s公共交换电话网”,“一条 512 kbps 的宽带连接”。
