To calculate the Shrink Percentage (S):
\[ S = \frac{OS - FS}{OS} \times 100 \]
Where:
Shrink percentage measures how much change in size occurred on an object that shrunk in size relative to the original size of that object.
Let's assume the following values:
Using the formula:
\[ S = \frac{100 - 90}{100} \times 100 = \frac{10}{100} \times 100 = 10 \% \]
The Shrink Percentage is 10%.
