How to compare negative currents in magnitude

[higherme]

I have a question about current

If i am comparing two currents which are both negative, how do i know which one is bigger

For example,
current 1 is -1.00E-6 V
current 2 is -4.00E-6 V

I'm guessing that current 2 is bigger, and the negative sign is ignored

am i correct?
help please

oops...
the above units should be in A(amp)

The sign only reflects the polarization of the electrode. The amplitude is given by the number. Which is larger, 0.000004 or 0.000001?
