The size of your erection varies every single time. Your size fluctuates constantly and it depends on many factors. It even depends on the temperature in the room. You will never get the same measurement twice (scientifically speaking). Whenever I give in a lab report, I must calculate the uncertainty on every instrument that was used during the lab.
So if you measure your penis and it comes to 7.00 inches (for example)..you will have to look at the uncertainty on your ruler, which could be something like 1/32 inch. So your measurement would be 7.00 more or less 1/32 inch.
Quote: "Each instrument has an inherent amount of uncertainty in its measurement. Even the most precise measuring device cannot give the actual value because to do so would require an infinitely precise instrument. A measure of the accuracy of an instrument is given by its uncertainty. As a good rule of thumb, the uncertainty of a measuring device is 50% of the least count. Recall that the least count is the smallest subdivision given on the measuring device. The uncertainty of the measurement should be given with the actual measurement, for example, 41.64 ą 0.05 cm. "

When you measure your penis, you will have to keep track of your physiological uncertainty. Depending on a variety of things, your erections will always fluctuate. How much blood is in the penis? How expanded is the tissue? The penis is a sponge therefore it's size and shape is always different. It's not like a tooth that is always hard (in fact, even your tooth size varies slightly). If you wanna get REALLY scientific, you can say that there is uncertainty in the way your eyes pick up the light photons which allow you to see the ruler and the measurement (the light in your room is another factor).
So you really dont have to worry so much about measuring every single day, because it'll be different.
