Mbps is bits per second
Storage is measured in bytes, so the calculator divides line rate by eight before applying the time window.
Capacity calculator
Translate bandwidth into actual monthly transfer.
Model sustained line rate and transfer time in both decimal and binary units, or work backwards from a transfer target.

Calculated values
Decimal and binary units
TB uses powers of 1000; TiB uses powers of 1024. The tool shows both rather than silently mixing them.
Real traffic is bursty
A sustained-rate estimate is useful for capacity planning but real applications usually vary by time of day and caching.
Protocol overhead is not modeled
Ethernet/IP/TCP/TLS overhead and retransmissions are intentionally not guessed here.
