## What is the Golden Ratio

The golden ratio, also known as the golden mean, is the value phi where phi = (A+B)/A = A/B.

## Golden Ratio Formulas:

For this calculator we use phi = ( 1 + sqrt(5)) / 2, which is rounded to 1.6180339887499. You can round your answers A and B to whole numbers or decimals up to 6 places.
