How long to transfer a file of size X over a Y Mbps line?

How long does it take to transfer a file of size X over a Y Mbps line?

A 1 MB file over a 1 Mbps line takes 8 seconds. Not 1 second, due to MegaBytes over MegaBits

1 GB over 1 Mbps = 8192 secs (8*1024; 2.2755 Hours)

1 TB over 1 Mbps = 8388608 secs (2,330 Hours = 97 days)

So a good rule of thumb to remember is:

1Tb over 1Mbps takes ~100 days (8 * 1,000,000 secs)

There are also good online calculators for this. For example:

Convert Megabits Per Second to Terabytes Per Month
