Bit
A bit (b) is the smallest unit of digital information. It represents a binary value of 0 or 1, the foundation of all data processing in computers and electronic systems. Bits are most commonly used to measure internet speeds, network bandwidth, and data transmission rates.
Because bits are so small, they scale up into larger units like kilobits and megabits for practical use. Converters help users translate network speed ratings into file sizes to understand how long downloads or streaming might take.
Gigabit
A gigabit (Gb) is a unit of digital data equal to 1,000 megabits or 1 billion bits. It is commonly used to describe high-speed internet connections, advanced networking equipment, and data center communications. As digital services grow, gigabit speeds are becoming more common in homes and workplaces.
Gigabits make it easier to express large data rates without long numbers. However, converting gigabits to gigabytes or megabytes requires precise math, and a converter removes the guesswork when comparing speed with storage capacity.
