PI Formula Syntax
Example Use Case
Inserting the value of π for circular or trigonometric calculations
Understanding the PI Formula
The PI function in Excel returns the mathematical constant π (≈3.14159), the ratio of a circle’s circumference to its diameter. It’s a no-argument function, providing a precise value for circular, trigonometric, or geometric calculations.
Use PI() to calculate a circle’s area (πr^2) or pair it with trig functions like SIN or COS. It’s a fundamental constant, baked into Excel for instant access—no need to memorize or type out digits.
Why Use PI?
PI is indispensable for anything round—think engineering designs, physics formulas, or even baking pan sizes. Its built-in precision ensures accurate results in circular math, making it a universal tool for spatial work.
Example with Sample Data
| Description | Formula | Result |
|---|---|---|
| Raw π | =PI() | 3.14159 |
| Area (r=2) | =PI()*2*2 | 12.56636 |
| Circumference (r=3) | =PI()*6 | 18.84956 |
PI delivers: raw value is ~3.14159, scales up for area or circumference. It’s a circular constant.
