Facebook Timeline Cover Image?

photoshop has an option to use pixels instead of inches. I'd give you specific directions, but it depends on where you're trying to set the dimensions... but no matter where you're trying to set the dimension, they let you choose between inches, cm, pixels, etc.... so just look for the drop down option where is says "inches" (or whatever measurement type you're using) when creating a new image or trying to resize your image or canvas.
