## Standard Form Calculator

Standard form calculator is used to convert the numbers into standard form by placing the decimal value in the number. It converts a long number into an easily readable standard form.

## How to use a standard form calculator?

To use this standard notation calculator, follow the below steps:

• Enter the number in the given input box.
• Press the Calculate button to see the result.
• You can reset the values by using the Reset

This standard form equation calculator will instantly show you the converted standard form of the given number. You can also use our scientific notation calculator and scientific notation converter to calculate the scientific notations.

## What is standard form?

If you are wondering what is a standard form in math, you are at the right place.

Standard form is used to reduce the difficulty in reading very large or very small numbers. The standard form of a number is any number between 1.0 and 10.0 multiplied by power 10, For example, `1.2× 102`

For a demonstration of standard form, take a look at the below examples:

Number: 85500000000000

`Standard form: 8.55 × 1013`

Number: 0.000458912

`Standard form: 4.58 × 10-4`

## How to write in standard form?

You can use our standard form calculator to calculate the standard form of any number. However, we will explain how to convert a number to a standard form manually. To convert a number to standard form, follow the below steps:

• Write down the number.
• Identify the decimal point in the number. If there is no decimal point in the given number, it is considered at the right side of the number after the last digit.
• After identifying the decimal point, move the decimal to the first non-zero digit in the number.

• Count the total number of digits you have moved to the decimal point. Multiply the number by 10 and raise the power of 10 with the total number of digits the decimal has moved. If the decimal is moved from right to left, power will be positive, and if the decimal is moved from left to right, power will be negative.

Example:

Convert 0.0009 to the standard form.

Solution:

Follow the steps to find the standard form of the given number.

Step 1: Write down the number.

`0.0009`

Step 2: Identify the decimal point in the number. You can see the decimal point is lying after 4 digits from the left side.

Step 3: After identifying the decimal point, move the decimal to the first non-zero digit in the number.

It will become 9. Because there is no non-zero digit after 9, we don’t need to write the decimal point after 9.

Step 4: Count the total number of digits you have moved to the decimal point.

We have moved the decimal 4 places further. Multiply the number by 10 and raise the power of 10 with the total number of digits the decimal has moved. As we have moved the decimal point from left to right, the power will be negative.

`9 × 10-4`

So, the standard form of the number 0.0009 is 9 × 10-4.

Examples:

 25*10^6 in standard form 2.5 x 107 5004300 in standard form 5.0043 x 106 0.00147 in standard form 1.47 x 10-3 0.884 in standard form 8.84 x 10-1 234.543 x 10^2 in standard form 2.34543 x 104
