Chord Calculator: Instantly Find Circle Chord Length

Calculate Chord Length from Radius and Central Angle

units
Enter the radius of the circle.
°
Enter the central angle subtended by the chord in degrees (0 to 360).

Need to determine the length of a chord in a circle? Our Chord Calculator simplifies this geometric task. Just input the circle's radius and the central angle subtended by the chord, and get the accurate length instantly. Perfect for students, engineers, and designers!

Formula:

The chord length (c) can be calculated using the formula:

c = 2r × sin(θ/2)

Where:
c = Chord Length
r = Radius of the circle
θ = Central Angle subtended by the chord (in degrees)
