## Die Per Wafer Formula

The following formula is used to calculate the die per wafer.

DFW = d * pi * ( 4/(4*S) – 1/SQRT (2*S) )

- Where DFW is the die per wafer
- d is the diameter of the wafer
- S is the die size (square)

## Die Per Wafer Definition

A die per wafer is defined as the number of dies per wafer area of a die-cut part usually square silicon pieces.
