So if your ISP mentions 512 Kbps , 1 Mbps , 2 Mbps , 4 Mbps ., to calculate your download speed in Bytes simply divide it by 8 , that will be your download speed in KiloBytes or MegaBytes . example
512 Kbps = 64 KB/s
1 Mbps = 1024 Kbps = 128 KB/s
2 Mbps = 2048 Kbps = 256 KB/s
4 Mbps = 4096 Kbps = 512 KB/s
