Since, 1 examiner is equal to [tex]{10^{18}}[/tex] miners, then by using this conversion factor between miner and examiner; the value given in miners can be determined in Eminers.
Therefore,
[tex]10^{15} miners = \frac{10^{15}}{10^{18}}[/tex]
= [tex]10^{15-18}[/tex]
= [tex]10^{-3}[/tex]
Thus, [tex]10^{15} miners[/tex] miners is equal to [tex]10^{-3}[/tex] Eminer (examiner).
