Its not Pi. Its has something to do with all the ratios in your body? I just cant remember that name of it or what it equals? Something about ratios of distance in your arms and legs being equal to it?

Phi, I believe is the word you are looking for. (Φ)
It represents the golden ratio which is (1+sqrt(5))/2 or the solution to the equation x^2-x-1=0. (1.618033).

It's called the golden ratio, often symbolized by the Greek letter Phi (Φ, or more often lower case Ï), which some pronounce "Fee" and some pronounce to rhyme with "Pi". It's specifically equal to (1+â5)/2. This is because the ratio is defined from a golden cut, which the cut you make on a line segment AC at a point B such that AC / AB = AB / BC, and you can use some geometery and algebra to calculate the ratio as exactly (1+â5)/2. Its reciprocal oddly enough is (1-â5)/2, or itself minus one.
Other names for it include "the divine proportion" and sometimes "the Fibonacci ratio" (since the ratios of consecutive numbers in the Fibonacci sequence approach Phi).

The golden ratio expresses the relationship that the sum of two quantities is to the larger quantity as the larger is to the smaller. It equals about 1,62.
Many artists and architects have proportioned their works to approximate the golden ratio because we usually find this proportion particularly aesthetic. Mathematicians have studied the golden ratio because of its unique and interesting properties.

The number you're looking for is PHI. It is approximately 1.618.
It's also called the "Golden Ratio," since it's found in the ratios in your body.

the Golden Ratio, related to the golden rectangle and a whole bunch of other stuff. I just went over that in my math class.
