About this tool

What Roof Pitch Converter does

The Roof Pitch Converter on Number Convert translates roof slope between three common formats: ratio, degrees, and percentage. Users input a measurement in any one of these units, and the tool immediately computes the equivalent values in the other two systems, ensuring accuracy for structural angles drawn from blueprints or specifications. The result provides all necessary data points for material ordering and construction planning. The Number Convert version distinguishes itself through a focused, three-field interface that requires only a single input to populate the other two formats. Unlike Omni Calculator, which computes rafter length and additional slope metrics, this tool concentrates exclusively on the ratio-degree-percentage triad. The live page includes a concise explanation of why pitch matters—linking inaccurate conversions to structural integrity, material choice, and water management—alongside practical examples of minimum pitch requirements for different roofing materials.

Questions

Roof Pitch Converter FAQ

Can I convert a roof pitch given in degrees to a ratio?
The tool uses standard trigonometric conversions between ratio, degrees, and percentage. Enter any one format and the other two values are calculated immediately using established mathematical relationships.
What does a 6:12 roof pitch equal in degrees and percentage?
The converter translates the rise-over-run ratio into both the angular degree measurement and the vertical rise as a percentage of the horizontal run.
Is this tool suitable for determining minimum pitch requirements for roofing materials?
By giving you the precise degree and percentage equivalent of any ratio, you can compare your roof slope against the minimum pitch specifications for asphalt shingles, metal panels, or other roofing materials.
Do I need to enter the run value of 12 for the ratio to work correctly?
The converter is designed to work with standard ratio inputs, but it can handle various ratio formats without requiring a specific run of 12 inches.
