hartley
n. countable C2 Proficiency US //ˈhɑɹtɫi// hart·ley
n. a unit used to measure information. One hartley is the amount of information you get from choosing one of ten equally likely options.
n. a logarithmic unit of information or entropy based on ten-state choices. Equivalent to the information content of one decimal digit, or approximately 3.322 bits.
The system measures data transfer in hartleys.
In early information theory, the hartley was used alongside the bit to quantify the capacity of communication channels.
While the bit remains the standard unit in modern computing, the hartley provides a useful base-10 alternative for specific logarithmic calculations in classical information theory.
Usage
Named after Ralph Hartley; often used in technical contexts involving base-10 logarithms.
