How to Use
Using the Degrees ↔ Feet Calculator is straightforward:
- Input Angle (degrees): Enter the angle of the arc in degrees. This is the portion of the circle you are interested in.
- Input Radius (feet): Provide the radius of the circle or arc in feet. The radius is the distance from the center of the circle to any point on its edge.
- Calculate Length: Click the “Calculate Length” button. The calculator uses the formula: L = (a / 360) * 2 * π * r
- a = Angle (degrees)
- r = Radius (feet)
- π = Pi (approximately 3.14159)
- View Results: The calculated length (L) is displayed, showing the distance along the arc in feet.
