MNE units are too high

I am loading in data from an ECoG experiment and realised that the scale is way too high.
To test this, I loaded in an array of only 1s (so everything is 1uV) of the same size to my original data and what I expect is that the average when using combined=‘mean’, should be one.

Except it’s not.
How can I fix the graph to reflect the correct units?

What does your data look like? Is it scaled correctly (i.e. 10-6)?

If by correctly scaled you mean that the value ‘1’ = 1uV, then yes.
I just realised I can simply multiply by 10e-6, sorry to bother you!

OK! MNE expects EEG units to be in V, so 1 = 1V.

MNE uses SI units in general just FYI e.g. m.
