Degrees (Angles) We can measure Angles in Degrees. Enter any angle or fraction of angle to find pitch. To convert between American roofing ratios and pitch degrees, follow these steps: Divide the first part of the ratio by 12 to work out the pitch. Plugging the angle value, in degrees, in the previous formula, we get: α rad = π × 30 /180 = π × 30÷30/180÷30 = π/6 radian, when reduced to lowest terms. Slope can be expressed in angles, gradients or grades. B-Z Baby Products for the Busy Baby.
