Had 60 digits memorized in high school to prove a point and now I only remember:

When I originally memorized this much (during a detention in 6th grade), I had the digit after that as a 6.

Maybe one day I'll memorize the next 15 correctly.

As an engineer, there are only two numbers you need to remember.

1) pi=3. If you're doing a quick estimation, that's all you need.

2) pi=4*atan(1). If you need something more than a quick estimation, you write a computer program. This is what is typically used.

Memorizing more than a couple digits is a complete waste of mental resources that are better spent doing something else.

Friend showed me this years ago, good if you don't have a Pi key on the calculator. Take the first three ODD digits, arrange in a row with repeats, then split in half like this:

113/355

Divide 355 by 113 = 3.14159292035 etc

good to 8 digits.
