Is there an alternate symbol for mu for x 10^-6 ?

[Nway]

Homework Statement:

I am confused about a notation highlighted shown below

Relevant Equations:

C = Q/V

Can someone tell me what that means? I'm think it should be a mu.

The highlighted symbol means "proportional to". You are correct in thinking it should be $\mu$. Some typesetter must have screwed up.

If TeX is not available and Greek letters are difficult to type people sometimes use "u" instead (uF = $\mathrm{\mu F}$). The "proportional to" (\propto, $\propto$) is just the wrong symbol.
