1. What is Pitch to Degrees Conversion?

The Pitch to Degrees conversion calculates the angle in degrees from the roof pitch expressed as rise in inches per foot of run. This is commonly used in construction, roofing, and carpentry to convert between different angle measurement systems.

2. How Does the Calculator Work?

The calculator uses the mathematical formula:

Where:

• \( Pitch \) — Rise in inches per foot of run
• \( \arctan \) — Inverse tangent function
• \( \frac{180}{\pi} \) — Conversion factor from radians to degrees

Explanation: The formula converts the pitch ratio (rise over 12 inches of run) to an angle using trigonometry, then converts from radians to degrees.

3. Importance of Pitch to Degrees Conversion

Details: Accurate angle conversion is essential for roof construction, stair building, ramp design, and any construction project where slope angles need to be precisely calculated and communicated between different measurement systems.

4. Using the Calculator

Tips: Enter the pitch value in inches per foot (e.g., 4 for a 4:12 pitch). The value must be positive and greater than zero. The calculator will output the corresponding angle in degrees.

5. Frequently Asked Questions (FAQ)

Q1: What is a common roof pitch in degrees?
A: A 4:12 pitch is approximately 18.43°, a 6:12 pitch is about 26.57°, and a 12:12 pitch equals 45°.

Q2: Why is pitch measured in inches per foot?
A: This traditional measurement system is practical for construction as it's easily measurable with a level and tape measure on site.

Q3: Can I convert degrees back to pitch?
A: Yes, use the formula: Pitch = 12 × tan(degrees × π/180)

Q4: What's the maximum possible pitch in this system?
A: Theoretically unlimited, but practically, most roofs range from 2:12 (9.46°) to 12:12 (45°).

Q5: Is this conversion accurate for all angles?
A: Yes, the trigonometric calculation is mathematically precise for any positive pitch value.
