```Without a short reproducible example your question is difficult to
understand, and difficult to give a useful answer.

No, 1e-4 does not equal 0.01831563.
1e-4 = 0.0001

Since it's not true I suppose you don't need to change the scale?

If the relative frequency of some bin is 0.0001, why would you want
to label it 0.01? That would be incorrect.

I find it somewhat difficult to produce a histogram, using hist(),
with a relative frequency scale, and with relative frequencies on the
order of 10 to the minus 4. This is another reason why a reproducible
example is necessary.
