    Diameter of a hydrogen atom is all well and good, but how many digits of pi will we need to be accurate to a Planck Length?

        The diameter of a hydrogen atom is over 10,000,000,000,000,000,000,000,000 plank lengths.

        So based on this post I have no idea.

          Well that’s only 26 more digits, so we’re probably good at 100 digits of pi. [citation needed]

            log_10(size of observable universe / planck length) = 61.74… so like 63 digits of precision for everything are enough

        The width of a hydrogen atom is 3.1*10^24 Planck lengths. So, yeah, 65 digits of pi ought to do it.
