## What is the Standard Form of a Number?

Before we proceed, we need to know what the standard form of a number is. When working in fields of natural science like physics, chemistry and biology, we often come across very large or very small numbers that are inconvenient to express in normal units like meters, seconds, or calories. Examples of such include interstellar distances, the weight of an atom, the number of bacterial cells, and so on. If expressed in regular decimal terms, these figures would be virtually unreadable.

Therefore, to make them easier to express, the scientific community proposed several alternatives. One such technique is the standard form of a number, also known as scientific notation or exponential form. It is a vintage mathematical approach used by mathematicians, engineers, and scientists for a long time.

For example, let’s say there are 1,280,000 atoms in a tiny grain of iron. Instead of writing down this number as such, we could express it in standard form in this manner – 1.28 x 10^{6}.

In the above example, we are dealing with a positive exponent which indicates a large number. Similarly, let’s say the diameter of a cell is 0.120000000 meters. In standard form, we could express it in this manner – 1.2 x 10^{-9 }meters. The negative exponent here indicates a small number.

## What is the Standard Form Calculator?

The standard form calculator is an online tool which can quickly and accurately display any number in the standard form. The number in question can be either in the decimal form or the integer form. As discussed above, the numbers we denote in standard form tend to be very large or very small. Thus, the scope for human errors during manual calculation is quite large. In scientific calculations, even a small calculation error can lead to an exponentially large difference. That is something we truly cannot afford.

Fortunately, with the help of the standard form calculator, you will be able to convert any number to the standard form in a reliable manner. It is programmed with an algorithm that guarantees accurate results. It is completely free to use, and features a user-friendly interface as well. As long as you have a properly working Internet connection, you will be able to access it from any place in the world.

## How to Use the Standard Form Calculator?

The standard form calculator can be used by following the steps given below:

- Open the calculator and enter a decimal or integer number in the input field.
- Click the Convert button to proceed with the conversion.
- You will soon see the standard form of the number you entered in the output field.

The standard form calculator is a helpful tool recommended to professional mathematicians, engineers, scientists, teachers, and students.
