Is the circumference formula accurate for girth

I am having troubles getting an accurate girth measurement when using the standard wrap around measuring technique so I was in my math class the other day looking in my book and noticed the circumference of a circle is 2 x pie x radius
So I measured the width of my penis which would be my diameter cut it in half a.k.a the radius and plugged it in

My width (diameter) = 1 5/8” or 1.625
My Radius = 1.625 /2 or 0.8125
Pie= 3.14

2 x (3.14) x (0.8125) = 5.1025 therefore my EG= 5.1025”
This number is about the average of my measurements? Do you guys think this is accurate or is the penis not circle enough to make a 100% correct measurement?
Has anyone who knew their girth tried this before and it came up as the same number?

Many guys have an oval shape - more width.

What problem are you having measuring?

It’s close enough, Shag. Like Hobby writes, penises are not perfect circles, but they are more oval shaped.

The formula for calculating the area or circumference of an oval accurately requires an understanding of calculus. Feck that!

Actually it’s more like an ellipse than a circumference. And you might want to use an accurate result of the pi number since you want at least 4 digits for your final result, due to the measurement of the inches (11/16=0.6875).

If you want to bother yourself:

Later.

Actually, the cross section comes closer to a triangular yield sign. Your cock is made up of three chambers and when you stack three cylinders together you get a yield sign shape. But estimating your girth as though it were a cylinder is close enough for government work (and buying the correct size vacuum tube for pumping).

Ramrod It’s close enough, Shag. Like Hobby writes, penises are not perfect circles, but they are more oval shaped.

Actually
All it is is 2 x pie x the square root of (( a^2 + b^2)/ 2) where a and b are the semi-axis lengths.
I guess it’s pre calculus but it doesnt take a rocket scientist so I will probaly try it later and tell you how it goes.

Okay, Shag. But the penis is not a perfect ellipse either.

P.S. Before you tackle calculus, you may want to try out the “quote” button when you quote other posters.

Didn’t we do a whole spiel on this when Size first set up the PE Database volume gizmo?

Shagnasty,

If you want the most accurate girth measurement, get yourself to Walmart or K-Mart and buy a tailor’s measuring tape in the fabric or sewing section. There’s too much variation in a dick’s shape to use a one-size-fits-all math formula for circumference.

Peforeal

I agree with PEforeal. You want accurate, an eighth inch is a big deal in PE and you don’t want it to be due to mathmatical error.

Cloth tape works just fine. If you don’t have one, cut a strip of paper about 1/4 inch wide, Hold it against a ruler and mark it at zero, and then again every 1/8 inch between 4.5 and 5.5, or whatever range is appropriate for you. The paper will conform to your shape.

It makes no sense to call your shape cylindrical or triangular or anything else, because it is not.
