    Excuse me what? I’ve been an engineer for a decade and have never met anyone that would do that. We have calculators.

      I think they mean napkin math. Like you’re in a meeting and they ask for a general idea if something will work or not

        I suppose. I’m still internally outraged and haven’t run into such a situation before, but I accept this.

        We all have phones with calculators, don’t really need to do napkin math anymore

          Depends on the level of precision you need. If I want the volume in a 500 foot long, 3 inch pipe to roughly estimate how much supply I need to order, I wouldn’t need a calculator. It would very roughly be 90-95 ft3. (Divide 500 by 4 two times and multiple by 3)

          Then I would spend 5 minutes double checking myself haha.
