Procedure for finding miller indices

The miller indices of a crystal plane are determined as follows:

STEP 1    :  Find the intercepts of the plane along the axes x, y, z ; Ex: 2, 2, 3.
STEP 2    :  Take reciprocals of the same ratio. Ex: 1/2, 1/2, 1/3.
STEP 3    :  Convert into smallest integers in the same ratio. Ex: 3, 3, 2.
STEP 4    :  Enclose in parentheses. Those are in the form of (h, k, l). Ex: (3, 3, 2).
