Enter a value for all fields
The Chord Length calculator computes the chord length based on the radius (r) and height (h).
INSTRUCTIONS: Choose units and enter the following:
- (R) Radius of Circle
- (h) Height of Arc (Chord to High Point - S+ee diagram)
Chord Length (L): The calculator compute the length in meters. However, this can be automatically converted to other length units via the pull-down menu.
The Math / Science
The formula for the chord length based on radius and height of chord is:
`L = sqrt(8h(r - h/2))`
where:
- r is the radius of a circle
- L is the length of the chord
- h is the height of the chord
