Primary Hashrate Units:
H/s : The smallest unit, performing one random hash collision per second, denoted as Hash/s or abbreviated as H/s
KH/s : 1KH/s = 1000H/s. K stands for Kilo, meaning 1,000 hash calculations per second
MH/s : 1MH/s = 1000KH/s. M stands for Mega, 1M = 1,000 thousand, meaning 1,000,000 hashes per second
GH/s : 1GH/s = 1000MH/s, meaning 1,000,000,000 hashes calculated per second
TH/s : 1TH/s = 1000GH/s, meaning 1,000,000,000,000 hashes calculated per second
PH/s : 1PH/s = 1000TH/s, meaning 1,000,000,000,000,000 hashes calculated per second
