Enlargement Ratio Formula
The following formula is used to calculate the Enlargement Ratio.
ER = (FS – IS) / IS *100
- Where ER is the Enlargement Ratio (%)
- FS is the final size
- IS is the initial size
How to Calculate Enlargement Ratio?
The following example problems outline how to calculate Enlargement Ratio.
Example Problem #1:
- First, determine the final size.
- The final size is given as: 25.
- Next, determine the initial size.
- The initial size is provided as: 10.
- Finally, calculate the Enlargement Ratio using the equation above:
ER = (FS – IS) / IS *100
The values given above are inserted into the equation below and the solution is calculated:
ER = (25 – 10) / 10 *100 = 150.00 (%)
Example Problem #2:
For this problem, the variables required are provided below:
final size = 60
initial size = 30
Test your knowledge using the equation and check your answer with the calculator above.
ER = (FS – IS) / IS *100 = ?
