How to use this tool
Convert decimal units (GB, TB) and binary units (GiB, TiB), then estimate data transfer time from data size and expected effective transfer speed.
Worked example
One decimal TB is approximately 0.909 TiB. Transferring 1 GB at 100 Mbit/s takes about 80 seconds without protocol overhead.
Interpreting the result
Do not confuse bits and bytes: one byte contains eight bits. Advertised link speed is usually higher than effective application throughput.
