How to use the square area calculator

The square area calculator is an essential tool for students, teachers, architects, and engineers who need to calculate the area of square surfaces. This calculator uses the basic geometry formula to calculate the area by squaring the side length.

Accurately measure the square's side
Enter the obtained value in the corresponding field, using meters as the unit of measurement
Make sure to use a period (.) as the decimal separator if needed
Click the 'Calculate' button to get the result in square meters and hectares
Use the share or print buttons to save or send the result

Formula for calculating square area

The calculation of a square area is performed using a simple formula that squares the side length. This is one of the most basic and important formulas in geometry.

Area = Side²

This formula considers that:

The square has all sides equal
The square has all angles as right angles (90°)
The area is the result of the side multiplied by itself

Practical calculation examples

For better understanding, let's analyze some practical examples of area calculation:

Square with side of 5m. Area = 5 × 5 = 25m²
Square with side of 10m. Area = 10 × 10 = 100m²
Square with side of 25m. Area = 25 × 25 = 625m²

Frequently Asked Questions (FAQ)

Why calculate the area of a square?

Calculating the area of a square is useful in various situations, such as in civil construction, architecture, decoration, landscaping, and even in calculations of materials such as flooring, painting, and coatings.

What's the difference between area and perimeter?

Area is the measure of the square's surface (the internal space), while perimeter is the sum of all sides (the square's outline).

When should I use this calculator?

This calculator is ideal for any situation where you need to calculate the area of a square surface, such as a plot of land, room, floor, wall, etc. It's especially useful for construction professionals, students, and teachers.

How to convert square meters to hectares?

One hectare (ha) equals 10,000 square meters (m²). To convert from m² to hectares, simply divide the value in square meters by 10,000. Our calculator performs this conversion automatically for your convenience.
