user65373: How does BAIKAL X10 make more money than AntminerS9 although BAIKAL X10 Only 10 GH/s and Antminer S9 14 TH/s ?
So, which one is bigger GH/s or TH/s?
I am confused.

user1307: GH/s stands for gigahash per second
TH/s stands for terahash per second
Giga- and tera- are SI prefixes just like kilo- and mega- and they are used everywhere (kilometer, megahertz, gigahertz, gigabyte, terabyte, ...). You can find the full list of SI prefixes here:

https://en.wikipedia.org/wiki/Metric_prefix#List_of_SI_prefixes

So, to sum up:
1 kH/s = 1000^1 = 1 000 hashes per second
1 MH/s = 1000^2 = 1 000 000 hashes per second
1 GH/s = 1000^3 = 1 000 000 000 hashes per second
1 TH/s = 1000^4 = 1 000 000 000 000 hashes per second
1 PH/s = 1000^5 = 1 000 000 000 000 000 hashes per second
1 EH/s = 1000^6 = 1 000 000 000 000 000 000 hashes per second
