Slope/Inclination Degree, Gradient and Grade Calculator
In metric countries it is common to use degrees or 10 or 100 as denominator. In the United States, slope is typically given in inches per 1 foot or as a ratio of inches per 12 inches and is often referred to with units of 'pitch'. Roof slope is the ratio between the vertical rise and the horizontal run:
The Gable Height of a roof with 30 feet run and vertical rice 6 inches per foot, can be calculated as VR = vertical rise (in/ft, cm/m) Example - Gable Height
