Ellipse Calculator

This CalcTown calculator calculates the focii, eccentricity, area and circumference of an ellipse.

X- Co-ordinate of center of the ellipse (x₀)

Y- Co-ordinate of center of the ellipse (y₀)

Semi-major axis (a)

Semi-minor axis (b)

Focus 1 x co-ordinate (F_x)

Focus 2 x co-ordinate (F'_x)

Focus 1 y co-ordinate (F_y)

Focus 2 y co-ordinate (F'_y)

Eccentricity (e)

Distance from center to focus (d)

Area of the ellipse (A)

m²

Circumference of the ellipse (C)

Where,

x₀, y₀ = center of the ellipse

a = semi-major axis length of the ellipse

b = semi-minor axis of the ellipse

F_x,Fy= 1st focus of the ellipse

F'_x,F'y = 2nd focus of the ellipse

e = eccentricity of the ellipse

d = distance from center to any one of the focii of the ellipse.

A = area of the ellipse.

C = circumference of the ellipse.
