Kilobit per Second (kbps)
A kilobit per second is 1000 bit/s. Audio streams are rated in kbps: MP3 at 128–320 kbps, voice calls at about 64 kbps.
Symbol: kbps
Quantity: data transfer rate (bandwidth)
SI relation: 1 kbps = 1000 bps (exact)
Derivation: 1 kbit/s = 1000 bit/s.
Exact: yes, by definition
Typical uses
- Audio bitrates (MP3, AAC)
- Voice over IP
- Old dial-up and 2G connections
