# To find the percent error in chemistry does the density being g/cm3 or g/mL make any change?

I have this word problem that says the density of the metal you measured is 8.85g/cm3 but the actual value for the density is 8.724g/mL.

Now I know the formula to calculate the percent error, but I don’t know if both the actual density and the measured one have to be both g/cm3 or both g/mL or it doesn’t matter, the steps would be the same?

This is my first time ever taking chemistry, we have not done this in class yet, this is a pre-lab exercise.

They just have to be the same units although in this case, 1 g/mL = 1 g/cm^3

So as long as they’re both measured in grams I’m good?
