Squaring the Ellipse - Calculator

Calculator for the edge length of a square and the semi-axes of an ellipse, if both have the same area. The calculation of the ellipse circumference is very complicated, for this see the ellipse calculator. Please enter either the edge length of the square and one semi-axis of the ellipse, or the two semi-axes. The other values will be calculated.

Area:

Round to decimal places.

The unit is the same for edge length and semi-axes. The area has this unit squared. For example, length in centimeters, area in square centimeters.

Example: square and ellipse with almost the same area. The semi-axes of the ellipse measure 90 and 63 pixels. The edge length of the square is 133 pixels.
