Calculating the square root of a number with a calculator is pretty straightforward. Use the calculator we’ve provided below to do the math.
Simply put, the square root of a number is the value that, when multiplied by itself, gives you the original number. For example, the square root of 16 is 4, because 4*4 = 16.

Why we use square root
Square roots have several practical applications, especially in geometry. For example, if you have a square area of 36 square meters, you know that each side is 6 meters because 6*6 = 36. Square roots are also used to solve quadratic equations, in statistics to calculate standard deviation and variation within a data set.
In finance, square roots are applied in volatility analysis to determine price movements of a stock or commodity. Bioengineers use square roots to interpret medical images and raw data with the help of algorithms. They are also used in science when working with right-angled triangles to find the hypotenuse.
In sports science, square roots play a role in assessing physical fitness and calculating medication dosages. This is done by determining body surface area from height and weight using specific parameters.
How to calculate square root on a standard calculator
Calculating the square root on a calculator is a straightforward process. Here’s how to do it:
- Start by entering the number for which you want to find the square root.
- Next, press the square root button. This button typically has the symbol “√” or might be labeled “sqrt.” On scientific calculators, you may need to press the “shift” or “2nd” key first to access the square root function.
After pressing the square root button, the calculator will display the result on the screen.
Example:
Let’s find the square root of 18:
- Enter 18.
- Press the square root button/”sqrt.”
- The result will be displayed, which in this case is 4.24.
