Convert Nibbles to Bits
Convert Nibbles (nibble) to Bits (b) instantly and accurately.
Conversion Formula
b = nibble × 4
About Nibbles
A nibble is exactly 4 bits = half a byte, representing 2⁴ = 16 values - one hexadecimal digit (0-F). Used in BCD encoding (each decimal digit = 1 nibble; 2 nibbles per byte packs two BCD digits), financial/mainframe packed-decimal formats, and CSS hex colours (#RRGGBB = 2 nibbles per channel). 4-bit processors (Intel 4004, TI TMS1000) processed one nibble per cycle. 1 nibble = 4 bits = 0.5 bytes.
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.
