Ever wonder how big your penis really is?

Hi,

This is my first post on this site I have been a member of the mens network forum for about 2 or 3 years. Anyway, I saw members talking about the combination of girth and length so I decided to put my 2 cents in about this.
I have done some calculations to determine penis volume percentile. Many of you know the way to find the volume of your penis but a simplified way to do this is (Girth squared / 4* Pi) * Length

I have calculated some percentiles for volume and they are the following:

50% = 11.62
55% = 12.25
60% = 12.88
65% = 13.58
70% = 14.33
75% = 15.21
80% = 16.21
85% = 17.43
90% = 19.00
95% = 21.57
97.5% = 23.92
99% = 26.90

See which range you are in. This should give you something to strive for! Happy gaining!

Are you sure your math is correct? I squared my girth (6.25x6.25), divided that (39.06) by 4, muliplied by Pi (39.06x3.14), and multiplied by my length (7" non bp), and got 858.5??? According to this post though, I'm definitely in the 99%
 
The formula should be:

(girth/2pi)squared x pi x length

So if you are 8x6 then your volume should be as follows:

(6/6.28)squared x 3.14 x 8 = 22.92 cubic inches

I've included an Excel that does this for you... I used this to track my gains for a while.

Yes, you will get the same thing if you do it this way but you have to make sure you are dividing by 4*Pi not dividing by four then multiplying by pi. This calculation is a just a little more simplified than the other but both are correct. I should have specified in the instructions. For you, 6.25*6.25 = 39.06 divided by 4Pi = 3.108 times your length 7 = 21.76. So above 95%!

Haha - 12.43. Talk about average. Oh well, I can go up to some chick and be like "Baby, I'm packing a cubic foot of wang"

Only if you take your measurements in feet. That's more likely 12 cubic inches. If you were packing 144 cubic inches then you could say you had a cubic foot.
 
What does the percentage relate to.

I am 6.50 x 5.00 => Vol = 12.9 in^3 =>60%

What does 60% relate to? 60% of what?

I think some of you guys are getting the girth and diameter mixed up.

girth = 2*pi*r = pi*d => d = girth/pi
area = pi*r^2 = pi*(d/2)^2 = (d^2 /4)*pi

now substitute girth for d,
area = [(girth/pi)^2 / 4]*pi
= [(girth^2 / pi^2)/4] * pi
= girth^2 * 1/(pi*pi)* pi /4
= girth^2 * 1/pi* 1/4
= girth^2/(4*pi)

where r = radius & d = diameter & r = d/2

= girth^2 * 1/pi* 1/4
= girth^2/(4*pi)

where r = radius & d = diameter & r = d/2
Actually... girth = circumference, not diameter.

A cubic foot is found by:

(1 ft)^3 = (12 in)^3
= (12^3)* in^3
= 1728 in^3
 
"Actually... girth = circumference, not diameter."



That's correct.

Where in my post do I said "girth = diameter"?

The proof shows how one can calculate "Area" using "Girth" or "Circumference" as an input. Normally, one uses diameter or radius to calculate area.
 
Devass, that is correct. 60% means that if you were to be in a group of 100 people, you would have a bigger penis than 60% and a smaller penis than 40% according to volume

Yeah I realized that as soon as I left my apartment to go get food. "Man I told that guy a square foot in inches, but we all make mistakes. We make even more of them when we are hungry or sleepy. :blush:

wait wait wait wait. So there are1728^3 in a cubic foot? Holy hell.
A cubic foot would be a box with the sides all a foot long. You should be pretty happy you aren't actually that big.

lol too funny :D:D:D
 
i just done it using that calculator that was posted and got 19.21

where does this place me ? where is the chart ? oh yeah, i put my bonepressed measurement in.

Or that shape either !
As another matter I'm curious about; On just what info are you basing these percentiles? I've read about quite a few studies dealing with length, but as we all know girth is a little harder to quantify.

Don't get me wrong, at 7x6 I am, according to your chart, right the fuck up there, I'm just wondering where ya got the data from.
 
kinsey study. I used the average length and girth attained in this study as well as the standard deviation given for length and girth. I am not sure if Kinsey is NBP or BP I have never really gotten a concrete answer from anyone.

Thanks for the example. I always fuck this up. That puts me at better than 23 cubic inches conservatively. Whahoooool!! I guess on a good day I'm at that magic 1 % of the population. I wish my common sense were in the same category!! <:(
