pi is the name given to the ratio between the circumference of a circle and the diameter.
Find a circle, measure the circumference (all around it) with a tape measure and then measure its diameter (the fattest bit in the middle)
then divide them (use a calculator)
pi = C / D
You should come up with a number somewhere close to 3
Computers have been busy calculating more and more decimal places of pi because it is an "irrational number" - the decimal numbers don't repeat themselves or have any pattern and just are the way they are.
All these people above telling you to use 3.14 or 3.14159265... whatever are pretty close to correct. They are, in fact, as close as you need to be.
But if you REALLY want to know what pi is, it is the constant ratio all circles have between circumference and diameter.

Long answer, Pi = how many diameter's can wrap around the circumferance of a circle. 3.14 is good enough for 7th grade.
If your curious, they still havent found the end of Pi. I think they're past 1 million digits though.

If you are asking about Pi,
it is the ratio of a circle's circumference to its diameter. The value is approximately 3.14159. It is an irrational real number.
