👉 "Piitis" is a term used in the context of mathematics and physics to refer to the ratio of a circle's circumference to its diameter. It can be defined as the ratio of the length of a circular arc to its radius, or equivalently, it can be understood as the circumference of a circle divided by its diameter. In mathematical terms, piitis is often expressed as the ratio of 2π (which is approximately equal to 6.28) to r, where r
