Time equals file size in bits divided by the rate in bits per second. The result is theoretical. Real transfers lose time to overhead, so you can enter an efficiency below 1.

1 min 20 sec

Theoretical time at the full rate.

With the efficiency you entered: 1 min 29 sec.

time (seconds) = (file size in bits) / (megabits per second × 1,000,000)

MB and GB are decimal (1,000). MiB and GiB are binary (1,024). Mbps stays in decimal megabits.

How this measurement works

MB and GB use powers of 1,000. MiB and GiB use powers of 1,024. Mbps is always decimal megabits (1,000,000 bits).
