Note. Network speeds use decimal SI multiples: 1 Mbps = 1,000,000 bits per second. Because a byte is 8 bits, a 100 Mbps connection downloads at about 12.5 MB/s.

How to convert Gbps to KB/s

To convert gigabits per second to kilobytes per second, multiply the gigabit per second value by 125000. You can also divide by 0.000008 to get the same answer.

kB/s = Gbit/s × 125000

Worked example

Convert 15 Gbit/s to kilobytes per second:

15 Gbit/s = 1,875,000 kB/s
