The "M" is in Mb is Million and the "K" in Kb is thousands. So "Mbps" is a Million Bit Per Second, and "Kbps" is Thousand Bits Per Second.
So 2Mb is the same as 2,000Kbps (both are 2,000,000 bits per second) and 8Mb is the same as 8,000Kbps (both are 8,000,000 bits per second)
So your reading of 953 Kbps is just UNDER 1,000 Kbps or just under 1Mbps (953,000 bits per second, just under a million)
The upload speed is 368Kbps so about a third of a Mbps. Upload speeeds is ALWAYS far lower than download speed.
