# Curve Calculator Surveying

In mathematics, the curve which does not cross itself is called as the simple curve. It is different from the curve. Triangles, quadrilateral, circle etc come under the category of closed curves. Here is the online curve calculator surveying which helps you to calculate the degree of curve easily. This simple circular curve calculator also gives you the value of the length of the curve, length of a tangent, external distance, length of a long chord and middle ordinate.

#### Formula:

l = π × r × i / 180
t = r × tan(i / 2)
e = ( r / cos(i / 2)) -r
c = 2 × r × sin(i / 2)
m = r - (r (cos(i / 2)))
d = 5729.58 / r
**Where,**
i = Deflection Angle
l = Length of Curve
r = Radius
t = Length of Tangent
e = External Distance
c = Length of Long Chord
m = Middle Ordinate
d = Degree of Curve Approximate
Use the above online simple circular curve calculator to find the approximate degree of curve in degree or radian within the fraction of seconds.
