Pi-ish Ratios: whole numbers that, as a ratio, approximate pi (π)

Since some large numbers are easier to remember than others, some large-numbered ratios could be both easy to remember and produce unexpectedly high pi-accuracy.

Bottom of the page, "355" is a relatively small default numerator. "20" is the default range of incremented denominators. For a specific numerator with a given range of denominators, the most accurate denominator is located near the range's center. If forgoing some pi-accuracy is okay, finding an easier-to-remember denominator might appear elsewhere within the given range. If incrementing large numerators is wanted instead, simply switch to incrementing numerators, supply an initial large numerator, click Update, and then each denominator will be of the highest-accuracy only.
