INTERNET SPEED: Some Confusion~

[zahn97]

Well, I am 14, cut me some slack if the answer is a simple one.

My D/Speed or Download Speed is roughly 1.5MB
HOWEVER, when I download something it says I am only downloading 171.5KB/s have a look.

Picture of speedtest.net STATING I have 1.42-1.50MB download:

Picture of Steam stating I am Downloading at 160-180KB/s:

Plus, If addition, the fact that this has been going on for over a year, and I haven't gone off and freaked out on my ISP is... well rather stupid, IF ANYONE, ANYONE could help me, I would be very grateful.
Perhaps I need to take this matter up with them?

You're confusing Megabytes per second with Megabits per second. The top image quotes your speed in Megabits. The download speed you see in Steam shows in Kilobytes or Megabytes per second.

1 byte = 8 bits.
