Why is 1 Ethernet (fast) not exactly equal to 100 Mb/s?

While Fast Ethernet nominally supports 100 Mbit/s, the converter uses a value reflecting actual data transfer rate conventions, which may differ from the nominal due to technical definitions and overhead.

What use cases benefit from converting Ethernet (fast) to Mb/s?

Conversions help in network speed comparisons, bandwidth planning, and evaluating facility or device connectivity in IT and telecommunications.

Does this conversion account for actual network throughput?

No, the conversion provides theoretical maximums. Actual throughput can be lower because of factors like network congestion and hardware limitations.

Key Terminology

Ethernet (fast): A family of IEEE 802.3 Ethernet standards providing a nominal 100 megabits per second data rate, commonly using twisted-pair copper or fiber optics for local area networks.
Megabit/second (Mb/s): A unit of data transfer rate representing one million bits transmitted per second, commonly employed to quantify network and telecommunications bandwidth.
Data Transfer Rate: The speed at which data is transmitted from one device to another, typically measured in bits per second.
