Since pitch is the rise over a 12 inch run divide the run by 12 to get the multiplier in this case 120 12 10.
The way pitch also known as roof slope is measured is rise over run.
We included a roof pitch chart below the 7 12 example image and the calculator below that.
This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.
