The formula to calculate the Characters Per Line (CPL) is:
\[ CPL = \frac{C}{L} \]
Where:
Let's say the total number of characters (C) is 1000 and the total number of lines (L) is 50. Using the formula:
\[ CPL = \frac{1000}{50} \]
We get:
\[ CPL = 20 \, \text{characters/line} \]
So, the characters per line is 20 characters/line.
