As a retired mechanical engineer, the joke is that we don't really remember the value of Pi, but we think it's somewhere around 3. But maybe we should use 4 just to be safe.
In any case, I have to remember 3.14 because one of my Daughters was born on Pi Day. Which, according her, is the second most important day of the year, just right behind Christmas Day, when she was growing up. So when she got into high school that meant that we had to bring enough pie to be served in each of her math classes on that day. (Oddly enough she prefers cheese cake over pie on her Birthday).
Now I'm not saying being born on Pi Day influenced her life any, but she has a PhD in Mech Engineering.
The last 4 years of my working life, I taught some math in my small rural local school. I introduced a tradition of calculating Pi from scratch by various "silly" means. All shamelessly stolen from Matt Parker of Standup Maths fame on Youtube. The students, (4th through 8th grade), were always highly entertained and may have accidentally learned some math.......
