I try to understand the Activity Monitor Network Data received/sec

From speedtest.net, I got almost 0.50 MBPS but from activity monitor the speed that I got never above 65KBPS even when browsing youtube.

Is 1 MBPS = 100 kpbs? Surely not because 1 mbps = 1000 kbps.

Inside
0.15Mbit/s is 153kbits/s which is 19.125Kbytes/s

Speedtest.net uses a different method of testing your download speed. It doesn't always saturate the link, thus Activity Monitor would only see a short up spike in usage.

The one it bit per second, the other one is byte per second.

0.15 Mbps = 150/8 kilobyte per second ~ 19 kb/s
Thanks. No wonder.
I have the internet package of 512 Kbps. from the speed test it show correctly 0.5 Mbps.

When downloading from internet/or viewing youtube, it max out at 65 kb/s
0.5 Mbps = 500/8 = 62.5 kb/s

Thanks, now I know how to calculate it.

1 Mbps not equal to 1000 kb/s.....

1 byte = 8 bits, just remember that and you'll be good to go.
