File Transfer Time Calculator
Find the line-rate duration of a general data transfer. Mix decimal or binary data sizes with bit- or byte-based rates without doing the unit conversion by hand.
A rate is not always written the same way
Mbps means megabits per second. MB/s means megabytes per second. Because one byte contains eight bits, 1 MB/s equals 8 Mbps before overhead.
transfer seconds = data size in bits ÷ rate in bits per second
Decimal units such as GB use powers of 1,000. Binary units such as GiB use powers of 1,024. Both are supported so the calculation can match the number shown by your source system.
