Hi Ryan, No, it is not in volts. It's also not something that one could tell from an image per se, but assuming you used ChimeraX to calculate Coulombic electrostatic potential, the units are kcal/(mol·e) at 298 K, as mentioned on this page: <https://rbvi.ucsf.edu/chimerax/docs/user/commands/coulombic.html> If you used APBS, DelPhi, or some other method, you should check the documentation for that method to verify what units they produce. I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

Hello,
I just want to verify that the electrostatic potential is measured in volts (V). Is this correct?
Here's an example of my analysis: <image.png>
Sorry to be a bother!
