kbps to kBps

I am reading an article and I think the author made a mistake. He wants to calculate the latency on the 56kbps WAN link. According to him 56kbps = 57344 bytes per second (56 * 1024). So the latency is 1538/57344 = 0.026820 seconds.
But isn't 56 kbps = 7168 bytes per second. Can somebody confirm that I am correct? Thanks

1 byte = 8 bits and 1 kilobyte = 1024 bytes

56 kbps = 56000 bps. Doesn't it give us 56000 / 8 = 7000 bytes per second?

Sure but then when I do convert 56kbps to byte per second through Google, it gives me the same answer as yours, which is 7168 bytes per second. So I am a bit confused. Is it 7000 bytes per second or 7168 bytes per second because for the conversion of 10mbps to bytes per seconds, Google gave me 12,500,000 bytes per second (10,000,000 bps / 8), which I agree. Thx

It looks like Google took the same conversion approach as Wiki for 10mbps. But for 56kbps, it took the 56 * 1024 to get bytes per seconds.

I agree that the difference is small. But I just want to be able to explain why we use (56 * 1024)/8 instead of 56000/8 in the kbps to byte per second conversion.

Yes. I am talking about transmission over a link.

tapanpattanaik,
Your calculation makes sense. You convert to KB then to bytes. Now how would you perform the calculation from 10mbps to bytes per second, based on the matrix in your reply.

I understand exactly what you are saying. But I am a bit confused for the conversion from bps to Bps.
For 100mbps, we have 100,000,000 bps / 8 = 12,500,000 Bps.
For 56kbps, why can't we have 56,000 bps / 8 = 7000 Bps instead of (56*1024) / 8 = 7168 Bps?
Any help with this?
