So, I learned in physics class at school in the UK that the value of acceleration due to gravity is a constant called g and that it was 9.81m/s^2. I knew that this value is not a true constant as it is affected by terrain and location. However I didn't know that it can be so significantly different as to be 9.776 m/s^2 in Kuala Lumpur for example. I'm wondering if a different value is told to children in school that is locally relevant for them? Or do we all use the value I learned?

9.8 is close enough to 10 for most human scale calculations. No need to have extra sig figs

Pi = 3

Sin(x) = x

And now, g = 10. Smh.

I have a "pi^2 = g" shirt, and every engineer I know loves it, every friend with a scheme background needs to point out that it's wrong.

I’ve seen engineers use all of these. Bridges still work

Yeah air resistance is a stronger factor than those .2 m/s2. If we can ignore it we can ignore both
