Squares are one of the most common geometric shapes in mathematics, design, and real-world applications. Whether you’re a student, teacher, engineer, architect, or DIY enthusiast, you often need to calculate the area or perimeter of a square. Doing the math manually can be time-consuming, especially if you’re working with multiple values or need precise results.
That’s where our S² Calculator comes in. This free online tool allows you to quickly calculate the area (S²) and perimeter (4 × S) of a square by simply entering the side length. You can also specify units such as cm, m, inches, feet, or any custom unit, making it a versatile companion for academic, professional, or personal use.
S2 Calculator
What is the S² Calculator?
The S² Calculator is a simple yet powerful tool designed to calculate the two most essential properties of a square:
- Area (S²): The space inside the square, measured in square units.
Formula: Area=S×S=S2\text{Area} = S × S = S²Area=S×S=S2 - Perimeter (4 × S): The total length around the square.
Formula: Perimeter=4×S\text{Perimeter} = 4 × SPerimeter=4×S
By entering just one value—the side length (S)—you’ll instantly get accurate results for both area and perimeter.
🔹 How to Use the S² Calculator
Using this calculator is straightforward and requires only a few steps:
- Enter the side length (S): Type the value of one side of the square in the input box.
Example:5 - Choose units (optional): You can specify units like
cm,m,in,ft, etc.
Example:cm - Click “Calculate”: The calculator will instantly display the results.
- Area (S²) →
25 cm² - Perimeter (4 × S) →
20 cm
- Area (S²) →
- Reset anytime: Use the “Reset” button to clear inputs and start again.
🔹 Example Calculation
Let’s say you want to calculate the area and perimeter of a square with a side length of 12 meters.
- Step 1: Enter
12as the side length. - Step 2: Enter
mas the unit. - Step 3: Click Calculate.
Results:
- Area = 12×12=144 m212 × 12 = 144 \, m²12×12=144m2
- Perimeter = 4×12=48 m4 × 12 = 48 \, m4×12=48m
