Angle Formula:
From: | To: |
The arc to angle calculation determines the central angle of a circle when given the arc length and radius. This is fundamental in geometry, engineering, and various technical fields where circular measurements are involved.
The calculator uses the angle formula:
Where:
Explanation: The formula converts the arc length to radians by dividing by the radius, then converts radians to degrees using the conversion factor.
Details: Calculating central angles from arc lengths is essential in engineering design, architecture, navigation, and manufacturing where precise circular measurements are required.
Tips: Enter arc length and radius in meters. Both values must be positive numbers. The calculator will compute the central angle in degrees.
Q1: What is the relationship between arc length and central angle?
A: The central angle (in radians) equals the arc length divided by the radius. To get degrees, multiply by 180/π.
Q2: Can I use different units for arc length and radius?
A: Yes, but both must use the same unit system (both metric or both imperial) for accurate results.
Q3: What if the radius is very large compared to arc length?
A: The angle will be very small. The formula works for all positive values where radius > 0.
Q4: Is this calculation accurate for real-world applications?
A: Yes, this is the standard geometric formula used in engineering and scientific applications.
Q5: Can this be used for partial circles and sectors?
A: Yes, this calculation specifically finds the central angle for any circular arc segment.
