How i convert the pixel to mm or cm values

Postby kesk32 » Thu Aug 31, 2017 6:09 am

I have an image which says 390x390 pixel area. Assuming the scaling is correct ( meaning 1cm on film = 1 cm on image), how do one go about calculating the actual width and height?

Does the screen resolution play any role in the calculations?

Thanks
