The length of a pencil that has not been sharpened, with the eraser, is about 7.5 inches. This does however depend on the brand, etc.
it actually depends on how long your rubber is. when you have measured the rubber, work out how many millimeters that is and you have your answer.
Millimeters or centimeters.
You can measure small lengths in millimeters. Length of a pencil, pen, eraser, length and width of a paper, sheet etc. can be measured in millimeters.
How many millimetres in a eraser
I would guess that the standard eraser would be 2 to 3 centimetres in length. This converted to millimetres would be 20-30 millimetres.

There are many things that can be measured in millimeters:- paper clips- width of an eraser- length of an eraser- length and width of a simple battery- length of a pencil lead- width of a switch in which we plug things- beads- fingernails- width of a small can- eyelashes- wire diameters- tube diameters- the buttons on a monitor, on a CPU or on a laptop- icons that appear on a monitor screen
Depends on the size of the eraser
12 in. I just measured one and it was 7 1/4 inches long without the eraser, and 7 1/2 inches with the eraser. Hope that helps. (unsharpened, of course)
