  • To find this, enter the value of the square's side or area.
  • The calculator will display the radius and area of the largest circle that can fit inside the square!

• Dimensions of a square with the same area as a circle:

  • To find this, enter the value of the circle's radius or area.
  • The calculator will display the side length of the square with the same area as the circle!

• Dimensions of a circle with the same area as a square:

  • To find this, enter the value of the square's side or area.
  • The calculator will display the radius of the circle with the same area as the square!

You can thus use this square-in-a-circle calculator in several different ways, depending on your need!

To know how to find the largest square in a circle using the square inside a circle calculator, do the following:

1. Key in the value of the circle's radius or area.

2. The calculator will find what size square fits in the circle using the formula:

   side length = √2 × radius

3. The side length and the area of the square inside the circle will be displayed!

In this manner, you can find the maximal square that you can draw within a given circle.

To know how to find the largest circle in a square using the square inside a circle calculator, do the following:

1. Key in the value of the side or area of the square circ*mscribed about a circle.

2. The calculator will find what size circle fits in the square using the formula:

   radius = side length / 2

3. The radius and the area of the circle inside the square will be displayed!

In this manner, when a square is circ*mscribing a circle, you can find the radius and area of the circle.

For a circle with radius r, a square with the same area will have a side length of r√π. So, for example, if a given circle has a radius of 10 cm, then a square with the same area as the circle will have a side length of 10√π cm.

Alternatively, we can also convert a given square to a round shape by doing the reverse operation.

It's interesting to note that we can approximate a square to a circle by incrementally increasing the number of sides to get regular polygons such as pentagon, hexagon, heptagon, octagon, etc. until we end up with a circle ⭕.

🙋 Explore the different properties of these regular polygons by checking out our pentagon calculator, our hexagon calculator, and our octagon calculator.

Converting a square to a circle refers to finding a circle with the same area as the square. So if we want to convert a square to a round figure, the radius of the resulting circle will be s/√π, where s is the side of the square.

If we have a square of side 10 cm, its area will be 100 cm². A circle with the same area will therefore have a radius of 10/√π, or 5.64 cm.
