IEC and SI Digital Data Units

Following are the popular Digital Data Units defined by International Electro technical Commission(IEC) and International System of Units(SI). All the conversion logic used in this website align with these standards.

Digital Data Storage Measurement Units : Smallest to Largest

Bit (b) is the smallest unit to measure digital data. Byte is commonly used as the smallest addressable unit of storage in many computer systems.

Basic Units
Bit (b) 0 or 1 (Basic Unit)	Nibble 4 Bits	Byte (B) 8 Bits

Below chart illustrates the comparison between these units.
