📐 Key Features for Piping Engineers

1️⃣ DEG / RAD Toggle (Most Important Feature)

This feature allows switching between Degrees and Radians, which is critical for piping calculations.

DEG (Degrees):

Use this mode for standard piping angles such as 45°, 90°, 22.5° and 11.25°.

RAD (Radians):

Useful for advanced mathematical modeling, curvature analysis and academic calculations.

👉 For most piping offset and angle calculations, DEG mode is recommended.

2️⃣ Trigonometric & Inverse Trigonometric Functions

Essential for:

Offset travel calculation

Miter angle determination

Slope and inclination analysis

Pro Tip:

To calculate the pipe angle from known rise and run, use the atan (inverse tangent) function.

3️⃣ High-Precision π (Pi) Constant

The π button provides a high-accuracy Pi value, ideal for:

Pipe circumference calculation

Cross-sectional area calculation

Volume-related piping formulas

📝 Practical Examples

Use the following examples to verify calculator performance:

Task	Formula / Key Sequence	Result
Calculate 45° Offset Travel	`Rise / sin(45)`	Travel Length
Pipe Circumference	`Pipe OD * π`	Circumference
Find Slope Angle	`atan(Rise / Run)`	Angle in Degrees
Pressure Area	`π * Radius ** 2`	Cross-sectional Area

💡 Quick Tips for Accurate Results

Always close brackets ( ) to avoid calculation errors.

Results are rounded to 8 decimal places, ensuring engineering-grade precision.

Use Backspace (⌫) to correct small mistakes instead of clearing the entire expression.

Keep the calculator in DEG mode for most piping and field calculations.
