Convert Bits to Kilobits
Convert Bits (b) to Kilobits (kbit) instantly and accurately.
Conversion Formula
kbit = b × 0.001
About Bits
The bit (b) is the fundamental unit of digital information - a single binary digit: 0 or 1. Coined by John Tukey in 1948; formalised by Claude Shannon. Physically realised as transistor states (SRAM/DRAM), magnetic domains (HDD), charge levels in NAND flash (MLC=2, TLC=3, QLC=4 bits per cell). Shannon entropy: a coin flip = 1 bit; a card drawn from a 52-card deck ≈ 5.7 bits. 1 bit = 1/4 nibble = 1/8 byte.
About Kilobits
A kilobit (kbit) = 1,000 bits (SI). Standard unit for connection speeds: dial-up 9.6-56 kbit/s; ISDN 64-128 kbit/s; early ADSL 256 kbit/s. VoIP codecs: G.711 = 64 kbit/s; Opus (WhatsApp, Discord) = 6-510 kbit/s adaptive. Bluetooth LE up to 1,000 kbit/s; Zigbee/Z-Wave 20-250 kbit/s. 'kbit/s' = strictly decimal 1,000 bits/s (ITU/IEEE). 1 kbit = 1,000 bits = 125 bytes.
