Kilobit
A kilobit (Kb) is a digital unit equal to 1,000 bits. It is commonly used in networking and telecommunications to measure data transfer rates. Because bits alone are too small for practical measurement, kilobits help express speeds in a way that is easier to understand without overwhelming numbers.
Kilobits fit naturally into the decimal-based structure used by most internet service providers. They relate closely to higher units like megabits, but converting to bytes or megabytes requires careful calculation, which makes a converter very useful.
Byte
A byte (B) is a standard unit of digital data equal to 8 bits. It represents a single text character or a small chunk of a file. Bytes are used to measure storage capacity in everything from documents to photos and software applications.
Since bytes scale cleanly into larger units like kilobytes and megabytes, they provide a practical base for understanding how much data a device holds. Converters help translate between bytes and bits when moving between storage and speed contexts.
