The image above represents engineering strain. To calculate engineering strain, two essential parameters are needed and these parameters are Extension (e) and Length (l).
The formula for calculating engineering strain:
Strain = e/l
Where:
Strain = Engineering Strain
e = Extension
l = Length
Given an example;
Find the engineering strain when the extension is 20 and the length is 5.
This implies that;
e = Extension = 20
l = Length = 5
Strain = e/l
So, Strain = 20 / 5
Strain = 4
Therefore, the engineering strain is 4.
Calculating the Extension when the Engineering Strain and the Length are Given
e = Strain x l
Where:
e = Extension
Strain = Engineering Strain
l = Length
Let’s solve an example;
Find the extension when the strain is 2 and the length is 8.
This implies that;

Strain = Engineering Strain = 2
l = Length = 8
e = Strain x l
Then, e = 2 x 8
e = 16
Therefore, the extension is 16.

Calculating the Length when the Engineering Strain and the Extension are Given
l = e / Strain
Where:
l = Length
Strain = Engineering Strain
e = Extension
Let’s solve an example;
Find the length when the engineering strain is 4 and the extension is 44.
This implies that;
Strain = Engineering Strain = 4
e = Extension = 44
l = e / Strain
Then, l = 44 / 4
l = 11
Therefore, the length is 11.
