SUMMARY
The Scherrer formula for calculating crystal size is expressed as D=0.9λ/βcosθ. In this formula, β (beta) must be in radians, while θ (theta) is in degrees. This distinction is crucial for accurate calculations, as the dimension of cos(degree) is in radians. Understanding these units is essential for applying the Scherrer formula correctly in crystallography.
