Data Unit Converter
Convert digital data units between binary (1024-based) and decimal (1000-based) instantly. Supports bits, bytes, KB–PB, and data transfer rates.
How the Data Unit Converter Works
Use this free Data Unit Converter to convert between bits, bytes, kilobytes (KB), megabytes (MB), gigabytes (GB), terabytes (TB), petabytes (PB), and data transfer rates. You can switch between decimal (1000-based) and binary (1024-based) systems, which are commonly used in storage devices, operating systems, and networking. The swap button quickly reverses the conversion direction, making it simple to compare values.
Frequently Asked Questions
Decimal units are based on powers of 1000, where 1 KB equals 1,000 bytes. Binary units are based on powers of 1024, where 1 KB represents 1,024 bytes. Storage manufacturers usually use decimal units, while operating systems often use binary calculations.
Manufacturers use decimal units (1 GB = 1,000,000,000 bytes). Operating systems usually display binary units (1 GiB = 1,073,741,824 bytes). This difference makes the available space appear smaller.
Data transfer rates measure how fast data moves over a network or device. Common units include Kbps, Mbps, and Gbps — where 1 Mbps equals 1,000,000 bits per second.
Yes. One byte always equals 8 bits. Bits represent binary values (0 or 1), while bytes represent a collection of 8 bits.
