You can put units into the unit-box with the default multiplier of 1.
If you operate in "W" and "A" then the default unit could be "V" for volt.
Correct answer would be fx '45.0 V'.
However '45.0' would also be correct answer (which is not what you want).
As a second unit you put 'mV' into the unit box and '1000' as the multiplier.
correct answer would also be '45000 mV'.
As a third unit option put 'kV' and '0.001' together.
Correct answer would also be '0.045 kV'.
Hope this helps a little.
Thank you so much for the info.
Have you had problems with tolerance when you put in the second unit? I have been having problems with too large a range.
Can't tell as I have not yet played too much with this question type.
But thanks for the warning - I will check it out very soon.
