Ideal payload transfer time · formula reference
Assume no protocol overhead or contention. MB and Mbps use decimal prefixes, not binary mebibytes.
Formula
Assume no protocol overhead or contention. MB and Mbps use decimal prefixes, not binary mebibytes.
time = payload bits / bit rate
Worked example
A 173 MB payload is sent over a constant 185 Mbps link. Use decimal MB and ignore overhead. Find transfer time. Round the final result to 4 decimal places if needed. Answer in s.
The payload is 1384 megabits. Divide by 185 megabits per second.
7.4811 s
