How to Calculate and Solve for Grain Size Determination: Relationship between ASTM number and Grain Size per Square Inch | Imperfection in Solids

Last Updated on January 13, 2023

The image above represents grain size determination.

To compute for average number of grains per square inch, one essential parameter is needed and this parameter is ASTM Grain Number (n).

The formula for calculating average number of grains per square inch:

No = 2(n – 1)

Where:

No = Average Number of Grains per Square Inch
n = ASTM Grain Number

Given an example;
Find the average number of grains per square inch when the ASTM grain number is 2.

This implies that;

n = ASTM Grain Number = 2

No = 2(n – 1)
No = 2(2 – 1)
No = 2(1)
No = 2

Therefore, the average number of grains per square inch is 2.
