Reference
How data transfer rate conversion works
Network speeds are usually quoted in bits per second, while file transfers often display bytes per second. This converter keeps the lowercase bit and uppercase byte distinction visible.
Values are converted to bit per second first, then from that reference into the requested unit. Keeping a single documented reference reduces inconsistent pair-by-pair constants.

Questions
Data Transfer Rate FAQ
What is the reference unit for data transfer rate conversions?
ConvertWin uses bit per second (bit/s) as the internal reference for this category, then converts to the selected output unit.
How accurate is this data transfer rate converter?
These are raw rates; protocol overhead, encoding, congestion, and storage performance affect observed transfer time.
