Hi,
i need to calculate download time for file which is 4GB and the speed is 43.2 kbps.
i know i have to divide file size by the speed and to change GB to KB but not sure how to change GB to kbps?

Kb means 1000 bytes
MB = 1000 KB
GB = 1000 MB = 1000000Kb
so 4 GB / 43.2 kb/s = 1000000/(43.2 kb/sec)
= 23148.1 seconds
divide by 60 to get into minutes, then by 60 again to get it into hours.

File sizes are given in bytes, while download speeds are given in bits.
4 GB = 4*1024 MB = 4*1024^2 KB = 4*1024^3 Bytes  4*1024^3*8 bits.
43.2kbps = 43.2*1000 bits per second.
The time required is 795.364s, or 220.935 hours.
Note that 43.2kbps is quite a low bandwidth.
