Hello,
I'm fairly new to Mathcad and I'm having some difficulties, I'm trying to plot the conductivity of intrinsic silicon as temperature increases. The problem that I'm having is using the units cm^-3. Mathcad keeps changing the units to 1/L, and that changes the values as well. I tried going into tool-> worksheet options and click on the unit system tab. Then I clicked custom and changed the length from Meters to cm, but that still didn't work. I have attached my worksheet. Please let me know what I'm doing wrong. Thank you for all your help
