The image above represents grain size number with magnification. To calculate grain size number with magnification, two essential parameters are needed and these parameters are **Average Number of Grains per Square Inch (N _{o})Â **andÂ

**Magnification (M).**

**The formula for calculating grain size number with magnification:**

N = N_{o}(^{M}/_{100})Â²

Where:

N = Grain Size Number with Magnification

N_{o}Â = Average Number of Grains per Square Inch

M = Magnification

Let’s solve an example;

Find the grain size number with magnification when the average number of grains per square inch is 4 and the magnification is 6.

This implies that;

N_{o} = Average Number of Grains per Square Inch = 4

M = Magnification = 6

N = N_{o}(^{M}/_{100})Â²

N = 4(^{6}/_{100})Â²

So, N = 4(0.06)Â²

N = 4(0.0036)

N = 0.0144

Therefore, theÂ **grain size number with magnificationÂ **isÂ **0.0144.**
